1. Important Safety Notes About Collision Repairs有关碰撞维修的重要安全注意事项
  Caution:注意：
♦  When performing vehicle body sheet metal welding, cutting, and grinding operations, you must wear protective clothing, goggles, gloves, and work shoes.进行车身钣金焊接、切割、打磨操作时，必须穿防护服、戴防目镜、戴好手套、穿好工作鞋。
♦  The welding area must be well ventilated.焊接区域必须通风良好。
♦  Before welding, the negative terminal of the 12V battery must be disconnected and the terminals must be covered.焊接前，必须断开蓄电池负极，并盖好接线柱。
♦  If sparks are likely to occur when working near the 12V battery, the 12V battery must be removed.若在蓄电池附近作业时可能产生火花，则必须拆下蓄电池。
♦  Before disassembling the vehicle components, the vehicle should be fixed to the car lift frame to avoid changes in the center of gravity of the vehicle and affecting operational safety.拆卸整车部件前，应将汽车固定到汽车举升架上，避免整车重心发生变化，影响操作安全性。
♦  Connect the ground wire of the welding device directly to the parts to be welded, making sure there are no conductive parts between the ground point and the welding point.将电焊装置的接地线直接连接到待焊接的零件上，操作时须确保接地点和焊接点之间无导电零件。
♦  The ground wire or welding electrode must not come into contact with the electronic control unit and wires.接地线或电焊电极不得与电子控制单元及导线接触。
♦  No unprotected cars should be parked in body repair areas as flying sparks could cause fires and damage paint and glass.车身维修区域内不得停有任何无防护的汽车，因为飞溅的火花可能引发火灾、损坏漆面和玻璃。
♦  Do not weld, braze, or solder any part of the air conditioning system that contains refrigerant, nor any other parts of the vehicle that may cause the air conditioning system components to rise in temperature, which may cause the air conditioning system to explode. If electric welding must be performed near the refrigerant hose, the refrigerant must be recovered because the invisible ultraviolet rays generated during the welding penetrate the refrigerant hose and cause the refrigerant to decay.不得焊接、硬钎焊或软钎焊含有制冷剂的空调系统的任何部件，同样也不可焊接可能导致空调系统部件温度升高的汽车上的其他部件，否则可能导致空调系统爆炸。若必须在制冷剂软管附近进行电焊焊接，则必须回收制冷剂，因为电焊时产生的不可见紫外线穿透制冷剂软管会使制冷剂发生衰变。
♦  When working on the airbag system or performing body calibration, the 12V battery ground wire must be disconnected; the ambient temperature of the airbag components must not exceed 100°C (212ºF).对安全气囊系统作业时或进行车身校正时，必须断开蓄电池接地线；安全气囊部件的周围温度不得超过100℃(212ºF)。
2. Important notes on welding type descriptions有关焊接种类说明的重要注意事项
  Caution:注意：
♦  Commonly used welding types include spot welding, gas shielded welding, and brazing.常用的焊接类型有点焊、气体保护焊、钎焊。
♦  The number of welding points must not be reduced when performing spot welding.进行点焊时不得减少焊点数量。
♦  When the spot welding device cannot be used normally, gas shielded welding can be used for plug welding after drilling.通常点焊装置不能进行时，则可钻削后采用气体保护焊进行塞焊。
♦  When spot welding is used, if it is a connection of three-layer panels and only the outer plate is replaced, the solder joints must be placed on the original solder joints.采用点焊时，如果是三层板件的连接，仅更换外板，则焊点须置于原始焊点上。
♦  When spot welding is used, single-row welds, double-row welds, and double-row offset welds can be generated.采用点焊时，可以生成单行焊缝、双行焊缝、双行偏置焊缝。
♦  When using gas shielded welding, lap welds, continuous welds, and continuous welds (intermittent) can be generated.采用气体保护焊时，可以生成搭接焊缝、连续焊缝、连续焊缝(断续)。
♦  Brazing is often used to weld and repair areas where tensile strength is not high and component thickness is relatively small.钎焊常用于焊接和修补抗拉强度不高、元件厚度比较小的区域。
