板状钛及钛合金的焊接保护通常采用“保护拖罩”对熔池后部焊缝进行保护,背面焊缝则采用“背面保护垫板”进行保护;对尺寸小、结构较复杂的零件,则在真空充氩箱内进行焊接。而小直径钛管(特别是蛇形管)的焊
Flat titanium and titanium alloy welding protection usually use “protection drag” to weld the weld pool to protect the back of the weld is the use of “back protection pad” to protect; small size, the structure of the more complex parts, The welding is carried out in a vacuum filled argon tank. The small diameter titanium tube (especially the serpentine tube) welding
