大型中厚板铝合金框架氩弧焊焊接工艺分析

Analysis on Inert Gas Welding Technology of Large Size and Mid-thick Plate Framework of Aluminum Alloy

通过系列试验确定合理的焊缝坡口、焊接顺序以及工艺余量,最终减少大型中厚板铝合金框架的焊接变形,满足了设计图纸要求。

Through a series of experiments, a reasonable weld groove, technical allowance and welding sequence were determined. The welding deformation on large size and mid-thick plate fiamework of aluminum alloy was reduced ultimately and the requirements of the design drawings were met.
