首先来说济南镀锌管的焊接应该具有参数稳定、调节灵活、满足焊接镀锌管工艺要求和安全可靠的性能。焊工是很重要的,必须要经过考试并取得合格证后才可从事钢结构工程的镀锌管焊接,而且合格证中也应该注明施焊条件、有效期限。而且焊丝和焊钉在使用前应清除油污与铁锈。在施焊前焊工应复查构件接头质量和焊区的处理情况,如不符合要求,应在修整合格后方能施焊。

First of all, the welding of galvanized pipe in Ji'nan should have stable parameters, flexible adjustment, meet the technological requirements and safe and reliable performance of galvanized pipe. The welder is very important. It is necessary to pass the examination and obtain the qualification certificate for the galvanized pipe welding of the steel structure engineering, and the qualification of the welding condition and the expiration date should also be indicated in the certificate. And the welding and welding nails should be cleaned up before the use of oil and rust. Before welding, the welder should check the quality of the joint and the treatment of the welding area. If it does not meet the requirements, it should be welded after finishing.

济南镀锌管

1、普通的冷镀锌管,镀锌层比较薄,这种情况下使用一般就是普通的电焊或者气保焊接,焊接前将镀锌管表面的镀锌层做打磨处理后焊接。

1, common cold galvanized pipe, galvanized layer is relatively thin, in this case the general use of ordinary electric welding or gas shielded welding, before welding the galvanized coating on the surface of galvanized pipe to do after grinding.

2、济南镀锌管不便于打磨但是需要带镀锌层焊接的话,就需要用气体保护接,采用50-6的焊丝焊接,但是这种情况下锌烧损比较严重。

2, Ji'nan galvanized pipe is not easy to wear but need to be welded with galvanized layer, it is necessary to use gas protection and 50-6 welding wire, but in this case zinc loss is more serious.

3、热镀锌的话,镀锌层偏厚的情况下用WE53的焊条氩弧焊焊接。

3, hot dip galvanizing, if the zinc coating is thick, argon arc welding of WE53 electrode will be used.
