1、深加工:易產生摩擦熱,故采用耐高壓、高耐熱方管同時成形結束時應去掉表面附著的油。
 
方管焊接:焊接前應清除焊接中的銹、油、水、漆等鋼焊條。點焊時間短于碳鋼點焊距離短,采用方管刷。焊接后,為了防止局部腐蝕或強度下降,表面進行處理或清洗。
 
2、切割和沖孔:由于方管的一般強度高于材料,所以沖壓和剪切需要更高的壓力,而刀與刀間隙是不準確的,不能發生剪切破壞和加工硬化,采用等離子或激光切割,當使用氣體切割或切割、熱影響區的磨削和必要的熱處理。

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.
