1、深加工:易产生摩擦热,故采用耐高压、高耐热方管同时成形结束时应去掉表面附着的油。
 
方管焊接:焊接前应清除焊接中的锈、油、水、漆等钢焊条。点焊时间短于碳钢点焊距离短,采用方管刷。焊接后,为了防止局部腐蚀或强度下降,表面进行处理或清洗。
 
2、切割和冲孔:由于方管的一般强度高于材料,所以冲压和剪切需要更高的压力,而刀与刀间隙是不准确的,不能发生剪切破坏和加工硬化,采用等离子或激光切割,当使用气体切割或切割、热影响区的磨削和必要的热处理。

1, deep processing: easy to produce friction heat, so the use of high-pressure, high heat-resistant square tube at the end of the formation should be removed surface attached to the oil. Square pipe welding: Before welding should remove welding rust, oil, water, paint and other steel electrode. The spot welding time is shorter than the spot welding distance of carbon steel, the square pipe brush is used. After welding, the surface is treated or cleaned to prevent local corrosion or strength reduction. 2. Cutting and punching: Because the general strength of the square pipe is higher than that of the material, stamping and shearing require higher pressure, while the knife and knife clearance are inaccurate, shear damage and work hardening can not occur, using plasma or laser cutting, when using gas cutting or cutting, heat-affected zone grinding and necessary heat treatment.
