The invention discloses an anti blocking type welding nozzle structure of gas shielded welding, which comprises a welding nozzle body, a high temperature resistant insulation protection layer arranged on the inner diameter of the welding nozzle body and a high temperature resistant anti blocking agent arranged on the inner diameter of the high temperature resistant insulation protection layer. The high temperature in the high temperature resistant insulation protection layer and the high temperature resistant anti blocking agent refers to the temperature of the melting pool. The anti blocking type welding nozzle structure of the gas shielded welding has the advantages of convenient processing, and the high temperature resistant insulation protection layer can prevent short circuit. When the welding slag is attached to the high temperature resistant anti blocking agent, it is convenient to separate the welding slag and the high temperature resistant anti blocking agent together with the high temperature resistant insulation protection layer, and the high temperature resistant anti blocking agent is not easy to be burned dry, which can extend the working cycle of the welding nozzle and has low operating cost; in addition, the working process Medium and high temperature resistant anti blocking agent will not smoke, and the working environment is relatively good.

气体保护焊的防堵型焊嘴构造及其焊接工艺
本专利技术涉及气体保护焊
,特别涉及一种气体保护焊的防堵型焊嘴构造及其焊接工艺。
技术介绍
气体保护焊是利用气体作为电弧介质并保护电弧和焊接区的电弧焊。气体保护焊以焊丝和焊件之间的电弧作为热源来融化焊丝与母材金属,并向焊接区域输送保护气体,使电弧、熔化的焊丝、熔池以及附近的母材金属免受周围空气的氧化作用。在焊接的过程中,焊接时产生的高温焊渣会附着在金属材料制成的焊嘴上,随着焊嘴上附着的高温焊渣的累积,会堵塞焊嘴。不仅影响保护气体向焊接区域的输送,使得气体保护作用失效,导致焊道中存在大量气孔,需要对焊接工件进行打磨补焊;更重要的是金属材料制成的焊嘴通过焊渣可能会与焊嘴中用于送焊丝的连接杆形成短路,损坏导电嘴;严重的甚至会导致导电嘴无法送丝。为了解决上述问题,现有技术中采用的是蘸涂防堵膏的方法。具体操作步骤为将焊嘴插入盛装防堵膏的容器内,焊嘴因为焊接带有热量,融化防堵膏,使得防堵膏附着在焊嘴表面形成保护膜,以防止焊渣附着。为了避免焊嘴与连接杆之间的短路,并且便于防堵膏附着在焊 ...
