电子束焊：electron beam welding 电阻焊：resistance welding 点焊: Spot w eld
对接接头(Butt joint); 搭接接头（Lap joint）；角接接头（Fillet weld）T型接头（T-joint/Tee joint）
最常用的是:对接接头（Butt joint is the most used one）不开坡口的对接接头（Butt joint without groove）
两焊件端面相对平行的接头（The joint whose welding suefaces of both wel ding parts are parallel is called butt joint.）
如果产品在厚度方向上不要求全焊透，可进行单面焊接，应必须保证焊缝的计算厚度H≥0.7δ，δ为板厚。如果要求产品在整个厚度上全部焊透，可在焊缝背面用碳弧气刨清跟后再进行焊接，即形成不开坡口的双面焊接对接接头。（If the product doesn’t need full penetration of welding, we can take single-si de welding, and must make sure that the caculating thickness is more than or equal to 0.7δ(δis the thickness of steel sheets),If full penetration of weld ing needed, we can use carbon arcgouging to back chipping at the back of weld, after which weiding can be taken, than the double-faced welding butt joi nt without groove is formed.）
厚钢板的焊接（Weiling of thick steel sheets）
开坡口的对接接头，用于钢板较厚而需要全焊透的焊件。
（Butt joint with groove is used for thick welding parts which is needed full penetration of welding）
. 坡口的几何尺寸(Geometrical dimension of groove) 坡口（Groove）坡口面（Groove face/surface）
焊件的坡口表面叫坡口面（The surface of groove is named groove face）
1.2 坡口面的角度和坡口角度（groove face angle and groove angle）
焊件表面的垂直面与坡口之间的夹角叫做坡口面角度（The angle between the
vertical surface of the welding part and the groove is called groove face angl e.
两个坡口之间的角度叫做坡口角度（The angle between the two groove faces is called gro ove face）.
1.3 根部间隙（Root opening/clearance）
在焊接前，接头根部之间留的预留的空隙叫根部间隙，根部间隙的作用在焊接打底
焊道时，能保障根部可以焊透。（The clearance obligated for joint before welding
is called root opning , whose function is to keep the root can be full penetrat ion
welded when backing weld is welded）.
1.4 钝边（Root face）焊件开坡口时，沿焊件方向未开坡口的端面部分叫钝边。
（When groove is made,the face without groove along the weiding part direction is called root face）
1.5 根部半径（Root radius）在J型、U型坡口底部的半径叫根部半径。
（The radius at the bottom of the J-groove or V-groove is called root radius）
根据坡口形状的不同，长用的有：I型（不开坡口），V型，X型，U型；
（For the different of groove shape, we can classify the groove mainly into I-groove(with out groove),v-groove,X-groove,U-groove.）
V型坡口是最常用的坡口形式，便于加工，焊接时为单面焊，不用翻转焊件，但焊后容易变形。
（V-groove is the most used one.which is easy to machine and no turn is needed, but dis tortion is easy to form）

氧气切割：应用最广泛的一种，有手工、办自动、自动三种方法。
（oxygen cutting：The most used one,Inluding mannul,semi-automatic and automatic opera tion.）焊缝（weld）
1. 焊缝的分类：对接焊缝（butt weld）,角焊缝（fillet weld）,塞焊缝（plug weld），
2.1 焊缝尺寸：焊缝的尺寸用一系列几何尺寸来表示：
weld dimension:（The dimension of weld is defined by a series of geometrical dimensi ons.）
⑴焊缝宽度（weld width）⑵余高（weld reinforcement）
⑶熔深（depth of penetration）⑷焊缝厚度（weld depth）
⑸角焊缝的形状和尺寸（The shape an dimension of fillet joint）：
①焊缝计算高度（weld caculating hight）②焊缝凸度（weld convexity）③焊缝凸度（wel
d concavity）
⑹焊缝成型系数（The coefficient of weld moulding
焊接工艺参数对焊缝成型的影响
（The affection of welding procedure parameter to weld formation）
焊接工艺参数：焊接时，为保证焊接质量而选定的诸物理量（如：焊接电流、电弧电压、焊接速度、线能量等）的总称叫焊接工艺参数。
（Welding procedure parameter：The floorboard of all physical terms(as weiding current,arc voltage,welding speed, energy definitions and so on)which are selec ted to ensure the welding quality when welding is taken is called welding proce dure parameter）
1、焊接电流：当其它条件不变时，增加焊接电流，则焊缝宽度和余高都增加，而焊缝宽度几乎保持不边。其原因是：
Welding current:When the other conditions don’t change, if the weld current is added,both the weld depth and weld reinforcement will increase, the weld width almost will not change. The reasons are:
⑴焊接电流增加时，电弧的热量增加，因此熔池体积和弧坑深度都随电流增加，所以冷却下来后，焊缝厚度就增加。
When the welding current is added, the quality of heat of the arc will increa se, so both the volume of molten puddle and the depth of arc crater will all in crease, and the weld depth will increase when the weld is cooling.
⑵焊接电流增加时，焊丝的熔化量也增加，因此焊缝的余高也随之增加。
When the welding current is added, the fusion quality of welding stick will in crease, so the weld reinforcement also will increase.
⑵焊接电流增加时，一方面是电弧截面略有增加，导致熔宽增加，另一方面是电流增加促使弧坑深度增加。由于电压没有改变，所以弧厂也不变，导致电弧潜入熔池，使电弧摆动范围缩小，就是促使容熔宽减小。由于两者的共同作用，实际上熔宽几乎保持不变。
When the welding current is added, on the one hand,the section of arc will mo re or less increase, so the fusion width will increase; on the other hand, the depth of arc crater will increase. For the welding voltage doesn’t change, so the arc length also will not change, and the arc will penetrate into the molten puddle, which will make the swing range small,so the fusion width will decreas
e. By the both effection,the fusion width is almost not changed practically.
2、电弧电压：当其它条件不变时，电弧电压增大，焊缝宽度显著增加而焊缝和余高将略有减少。这是因为电弧电压增加意味着电弧的长度增加，因此电弧摆动范围扩大而导致焊缝宽度增加。同时，电弧增长后，电弧的热量损失加大，所以用来熔化母材和焊丝的热量减少，相对焊缝宽度和余高就略有减少。
Arc voltage: :When the other conditions don’t change, the arc voltage is added, the weld width will increase notably,but theweld depth and weld reinforcement will decrease smally.This is beacause that the the addation of arc voltage mean s the decreasement, so the enlargement of are swing makes the increasement of w eld width. Meanwhile, as the growth of arc, the lost of arc heat quality become s larger, so the heat quality which is used to fuse base meta l and weld stick d ecreases, the weld width and weld reinforcement decreases comparatively.
3、焊接速度（welding speed）
焊接速度对焊缝厚度和焊缝宽度有明显的影响，当焊接速度增加时，焊缝厚度和宽度都大为下降，这是因为焊接速度增加时，焊缝中单位时间内输入的热量减少。
The welding speed have evident effection on weld depth and weld width, when wel ding speed is added,both weld depth and weld width will decrease, for the input ed heat per time is limited.
4、其它因素：
①电极直径和焊丝外伸:electrode diameter and welding stick outside elongation
②电极（焊丝）倾角：elecrode(stick) obliquity③焊件倾角:welding parts obliquit y④坡口形状:groove shape
⑤保护气体成分: elements of protective gas ⑥焊剂: welding flux ⑦母材的化学成分: elements of basic meta l
焊接电弧（welding arc）：
电弧是一种空气导电的现象，在两极间强烈而持久的放电现象称为电弧。
Arc is the phenomenon of electric conductivity in the atmosphere, the fierce an
d permanent phenomenon of electricity discharg
e is called arc.

第八节
焊接应力与变形
1、内应力：内应力是在没有外力条件下平衡于物体内部的应力。
Inner stress：Inner stress is the stress which balances the object interior wit hout exterior stress.
2、变形：物体在某些外界条件下的影响下，发生形状和尺寸的变化。
Deformation：The object has changements of shape and dimension under some influ ences of outside conditions.
变形的分类：自由变形（free deformation）; 外观变形（visual deformation）; 内部变形（inner deformation）
3、焊接残余变形（welding residual deformation）的分类
⑴ 纵向收缩变形：构件焊后在焊缝方向上发生的收缩。
Longitudinal contraction deformation：The component contracts in the weld direc tion after weiding.
⑵ 横向收缩变形：构件焊后在垂直焊缝方向上发生的收缩。
Transverse/cross/lateral contraction deformation：The component contracts in th
e upright direction o
f weld after weiding.
⑶ 弯曲变形：构件焊后朝一侧弯曲的变形。
Bending deformation：The component bends in one side after welding.
⑷ 其它：
①角变形：（angular deformation）②波浪变形：（wave-like deformation）
③错边变形：（mismatching deformation）④扭曲变形：（deflection deformation 焊接残余变形的因素（the reasons of welding residual deformation）
1、焊接位置：如果焊缝在结构布置对称，焊接顺序合理时，则主要产生纵向收缩和横向收缩变形，反之，则要发生弯曲变形。
Welding position: If the configuration collocation of weld is symmetry and the welding sequence is reasonable, the longitudinal contraction and transverse lat eral contraction deformation are usually produced, incontrast, the bending defo rmation is usually produced.
2、结构刚性：结构抵抗变形的能力叫刚性。刚性大的结构焊后变形小。结构的刚性取决于结构截面的形状、尺寸和布置，截面积越大，长度越短，刚性越大。
Configuration rigidity: The capability of resisting deformation of configuratio n is called rigidity,.the configuration whose rigidity is large has less deform ation. The rigidity of configuration depends on the shape,dimension and colloca tion of configuration secyion, if the secyion is large and the length is shorte r, the rigidity will be larger.
3、装配—焊接顺序：将结构总装后进行焊接，由于结构刚性增加，可以减少焊后变形。Assembly—welding sequence:The configuration which had been whole assembled can decrease welding deformation for configuration rigidity had been added.
4、坡口长度和形式：焊缝越长，焊接变形越大，坡口内空间越大，变形越大。
Groove length and shape: If the weld is longer or the the vacuum of groove is l arger, the welding deformation will be larger.
5、焊接线能量：焊接线能量越大，焊接变形越大。
Welding energy definition: If the Welding energy definition is larger ,the weld ing deformation will be larger too.
控制焊接残余变形的措施
The measures of control welding residual deformation.
1、设计措施：正确的设计方案是控制变形的根本措施。
Design measure: The right design scheme is the basical measure to control the d eformation.
⑴ 选用合理的焊缝尺寸：增大焊缝尺寸，变形也会变大；但过小的焊缝尺寸，将降低裂纹的承载能力，使接头的冷却速度加快。
Choosing the reasonable weld dimension: The defornation will be increased when weld dimension is added;but if the weld dimension is too small, it will decreas
e reduce the load ability o
f weld and quicken the coolin
g speed of joint.
⑵ 尽可能的减少焊缝数量：适当选择板壁的厚度，可减少焊后变形矫正量。
Decrease the weld number as possible: Choosing the right thickness of steel pla te can reduce the rectification amount after welding!
⑶ 合理安排焊缝位置： Arr ange the weld position reasonably: ⑷ 预留收缩余量：Re main the contraction in advance.
⑸ 留出焊接夹具的位置：Remain the position of welding clamp in advance.
控制焊接残余变形的措施
The measures of control welding residual deformation.
2、工艺措施（Procedure measure）
⑴选择合理的装配—焊接顺序
Selecting the right assembly—welding sequence.
不同的装配—焊接顺序，焊后产生不同的残余变形，一般是先点固，再进行对称焊接。Different assembly—welding sequence may result different risidual deformation, we usually take fixup by spot welding first, then take welding symmetrically.
⑵选择合理的焊接顺序
Selecting the right welding sequence.
①采用对称焊接Take symmetrical welding.
②焊缝不对称时先焊焊缝少的一侧When the weld is not symmetrical, we should weld th
e side which has less weld.
③选择合理的焊接方向Selecting the right welding direction.
从中间向两端逐步退焊法变形最小，采用逐段跳焊法也可以减少变形。
Take welding from middle to both ends step by step may have the least deformati on, or take welding from one section to another step by step may also reduce th
e deformation. ④反变形法anti-deformation
⑤刚性固定法rigidity fixed method⑥选择合适的线能量Selecting the right welding ener gy definition
焊后残余变形的矫正方法
1、机械矫正法：机械矫正法是利用机械力的作用来矫正变形，可以用手工锤击或机械压
力。
Machine rectification: Machine rectification is using machine power to rectify deformation, which can be taken by hand hammering or machine pressure.
2、火焰加热矫正法：火焰加热矫正法是利用火焰局部加热时产生的塑性变形，使较长的金属在冷却后收缩，以达到矫正的目的。火焰采用氧—乙炔火焰或其它可燃气体火焰，这种方法设备简单，操作容易，但难度较大。
Flame rectification: Flame rectification is using plasticity rectification of s ome parts which is caused by heating of flame to make the meta l contraction aft er cooling, by which the purpose of recitification can be achieved. The flame u se oxyacetylene or other burnt gases , for this method, the equipment is simple, the operation is easy, but the difficulty is large.
焊接残余应力(Welding residual stress)
1、焊接残余应力的分类
①线应力：应力在构件中只沿一个方向发生叫线应力，也称单向应力。
Line-stress: The stress which only has one direction in the component is called Line-stress, which is also called single-face stress.
②双面应力：应力存在于构件中一个平面内的不同方向上，也称双向应力。
Both-faces stress: The stress exists in different directions in one plane of th e component is called Both-faces stress, which is also called double-faces stre ss.
③体积应力：应力在构件结构中沿空间三个方向上发生，也称三向应力。
Volume-stress: The stress exists in three directions in the volume of the compo nent is called Volume-stress, which is also calle
1、设计措施(Designing measure)
⑴尽量减少焊缝的数量和尺寸
Reduce the number and dimension of weld as more as possible.
⑵避免焊缝过分集中：焊缝过分集中将使应力叠加在一起。
Avoiding serious collection of weld: Serious collection of weld will make the s tress added together.
⑶采用刚性较小的接头形式：刚性结构增加时，焊接应力随之增大，因此，为减少焊接应力，应尽量采取刚性较小的焊接形式。
Using lthe joint which has less rigidity: When the rigidity of component is inc reased, the welding stress will also increase, so we should use the welding for m which has less rigidity to decrease the welding stress.
2、工艺措施(Procedure measure)
⑴采用合理的焊接顺序和方向
Using reasonable welding sequence and direction.
①先旱收缩梁较大的焊缝，使焊缝能较自由收缩。
Welding the weld which has more contraction first, which will make the weld con tract freely.
②先焊错开的端焊缝，后焊直通长焊缝。
Welding the welds which are stagger first, then is the straight ang long weld.
③先焊在工件上受力较大的焊缝，使内应力合理分布。
Welding the weld whiich suffers more stress first, which will make the stress h as reasonable distribution.
⑵降低局部刚性：焊接封闭焊缝或其刚性较大的焊缝时，可以采取反变形法来降低结构的局部刚性。
Reducing partial rigidity: When closed weld or the weld which has less rigidity are welded, we can take anti-deformation way to reduce the partial rigidity of component.
⑶锤击焊缝区法：Hammering the weld zone. ⑷预热法：Preheating⑸加热减应区法: He ating the stress-decreased zone.
消除焊接残余应力的方法
The way to remove welding residual stress
1、整体高温回火（消除应力退火）
回火温度越高，时间越长，应力就消除的越彻底，整体高温回火是生产中应用最广泛的一种方法。
Integrative high-temperature temper
If the temperature of temper is higher and the time is longer, the stress will be removed more throughly, integrative high-temperature temper is the most used one.
2、局部高温回火
只对焊缝及其附近的局部区域进行加热以消除应力，适用于结构比较简单、拘束度小的焊接结构。
Partial high-temperature temper: The area is only in the weld and its near area where is heated to remove stress,. This method is used for the welding constru ction whose construction is simpler and the constraint degree is smaller.
3、机械拉伸法
产生焊接残余应力的根本原因是焊件焊后产生了压缩而变形。因此，焊后对焊件进行加载拉伸，产生拉伸塑性变形而残余应力也随之减小。其很适用于焊接容器。
Machine stretching
The basic reason of welding residual stress is the contraction deformation afte r welding.So, we load and stretch the welding components after welding can make tensible stretching deformation,by which the residual stress will also decreas
e. This way siuts to welding container.

常用焊接英语术语
常用焊接术语 在实际应用过程中，经常会碰到一些与焊接相关的术语，行话，总结如下： 正极性指直流焊接时，被焊物接（＋）极，焊条、焊丝接（－）极 反极性与正极性相反 直流电弧焊或电弧切割时，焊件与焊接电源输出端正、负极的接法称为极性。极性分正极性和反极性两种。焊件接电源输出端的正极，电极接电源输出端的负极的接法为正极性（常表示为DCSP）。反之，焊件接电源输出端的负极，电极接电源输出端的正极的接法为反极性（常表示为DCRP）。 欧美常常用另外一种表示方法，将DCSP称为DCEN，而将DCRP称为DCEP。 焊接电流为向焊接提供足够的热量而流过的电流 电弧电压指电弧部的电压，与电弧长大致成比例地增加，一般电压表所示电压值包括电弧电压及焊丝伸出部，焊接电缆部的电压下降值。 弧长弧部长度 弧坑在焊缝终点产生的凹坑 气孔熔敷金属里有气产生空洞 飞溅焊接时未形成熔融金属而飞出来的金属小颗粒 焊渣焊后覆盖在焊缝表面上的固态熔渣 熔渣包覆在熔融金属表面的玻璃质非金属物 咬边由于焊缝两端的母材过烧，致使熔融金属未能填满，形成槽状凹坑。 熔深母材熔化部的最深位与母材表面之间的距离 熔池因焊弧热而熔化成池状的母材部分 熔化速度单位时间里熔敷金属的重量 熔敷率有效附着在焊接部的金属重量占熔融焊条、焊丝重量的比例 未熔合对焊底部的熔深不良部，或第一层等里面未融合部 余高鼓出母材表面的部分或角焊末端连接线以上部分的熔敷金属 坡口角度母材边缘加工面的角度 预热为防止急热，焊接前先对母材预热（如火焰加热） 后热为防止急冷进行焊后加热（如火焰加热） 平焊从接头上面焊接
横焊从接头一侧开始焊接 立焊沿接头由上而下或由下而上焊接 仰焊从接头下面焊接 垫板为防止熔融金属落下，在焊接接头下面放上金属、石棉等支撑物。 夹渣夹渣是非金属固体物质残留于焊缝金属中的现象，夹杂物出现在熔焊过程中 焊剂焊接时，能够熔化形成熔渣和气体，对熔化金属起保护和冶金处理作用的一种物质。 碳弧气刨使用石磨棒或碳棒与工件间产生的电弧将金属熔化，并用压缩空气将其吹掉，实现在金属表面上加工沟槽的方法 保护气体焊接过程中用于保护金属熔滴、熔池及焊缝区的气体，它使高温金属免受外界气体的侵害 焊接夹具为保证焊件尺寸，提高装配精度和效率，防止焊接变形所采用的夹具 焊接工作台为焊接小型焊件而设置的工作台 焊接操作机将焊接机头或焊枪送到并保持在待焊位置，或以选定的焊接速度沿规定的轨迹移动焊剂的装置焊接变位机将焊件回转或倾斜，使接头处于水平或船行位置的装置 焊接滚轮架借助焊件与主动滚轮间的摩擦力来带动圆筒形（或圆锥形）焊件旋转的装置
