摘　　要：用气保焊(GMAW)工艺焊接高强钢结构,考虑到某些具体要求,能充分利用母材和填充材料的优势。不同的焊接工艺有不同的性能,像喷射电弧,脉冲电弧,双丝和激光。掌握关于热输入和工艺流程知识可使这些焊接机使用起来更为简单,减少熔池区域、熔度不够和变形的风险。对掌握带有新的稳定(熔深稳定和弧长稳定)参数的工艺流程的各种可能性进行解释的同时,现代焊机可以通过设置焊接参数和热输入量来决定焊缝的生成。High strength steels constructions, joined with Gas-Metal-Arc-Welding （GMAW） processes, can take the advantage of base and filler material if some hints are considered. Different welding processes like Spray Arc, Pulsed Arc, Tandem and Laserhybrid, have different properties. Knowledge about heat input and process behavior make the usage of these wehting processes easier and reduce threats like softening zone, lack of fusion and undercuts. The different possibilities to steer the process properties with new stabilizer parameters like the penetration-stabilizer and the arclength-stabilizer are explained. Modern power sources also offer a wehl seam documentation of weld parameter and heat input.
