Welding glossary
There are many technical terms used for welding. The following table lists basic welding terms. There may be other terms specific to individual welding methods.
| Term | Description |
|---|---|
| B | |
| Base material | Material to be welded in a process where a filler material is used. When a filler material is not used, it is called "weld material." |
| 珠子 | 关节表面的高度由成品焊接组成。 |
| 光束扫描焊接 | 使用偏光镜将激光束应用于焊接点的方法。术语“梁扫描焊接”来自激光束横穿（“扫描”）固定材料的方式。 |
| Butt welding | A welding technique that makes the surfaces of the weld joint and base material almost flush with each other. |
| F | |
| Filler material | 电线或用于连接基本材料的焊丝。 |
| 鱼片 | A weld joint with a triangular cross section that joins two surfaces together at approximately 90 degrees. |
| Flux | 用于清洁和激活基本材料表面并改善填充物材料的流动性的材料。 |
| 烟 | Solid particles formed when a solid vaporizes once and then condenses through rapid cooling. |
| G | |
| Groove | A beveled opening created in a weld joint before welding to achieve necessary penetration. |
| H | |
| 热影响区（HAZ） | 基本材料的面积没有融化，但其微结构和特性在焊接过程中会改变。 |
| I | |
| Ionizing voltage | The voltage at which the outermost orbital electrons in an atom become ionized (sent outside the atom). |
| J | |
| Joule heat | 当电流流过导体时，通过电阻在导体内产生的热量。 |
| M | |
| Manipulator | A robot that operates with a multi-joint structure and a servo motor. The movable range varies depending on the number of joints (axes). It can be used for various operations through the replacement of hand pieces attached to the end. |
| P | |
| Pass | One welding progression made along a weld joint. |
| Penetration | The distance between the top of the base material melted by welding and the original surface of the base material. |
| Plasma (laser-induced plume) | A gas containing charged particles generated by ionization. |
| S | |
| Shielding gas | Gas used to block out atmosphere in order to prevent the oxidization or nitriding of molten metal during welding. |
| Slag | Non-metallic substances that form on the weld. The molten slag remaining inside weld metal is called slag inclusion and is a welding defect. |
| 溅 | The scattering of slag or metal droplets during welding which typically degrades welding quality. |
| T | |
| 量身定制的空白（TB） | Material for press working created through the welding of combinations of multiple steel sheets with different materials and properties to enhance strength and anticorrosion properties.
|
| W | |
| Weaving | 焊接运动泰pically used for arc welding that moves the torch from side-to-side almost perpendicular to the weld line. This motion can deposit more weld metal with fewer passes. |
| Welding defect | A defect resulting from abnormal welding caused by the inclusion of weld metal, inappropriate welding technique or welding parameters.
|
| Weld joint | A joint between base materials. |
| Weld line | A line representing a bead or a weld. A line to be welded, a line being welded or a welded line. |
| Weld pool | A puddle of molten metal created after the electrode or base material is melted by arc heat or other causes during welding. |
