Embodiment Construction

[0023] The present invention will be further described below in conjunction with embodiment:

[0024] A steel structure welding process, comprising the following steps:

[0025] 1), flat welding

[0026] 1.1) Clean up the welding joint: check whether the groove and assembly gap meet the requirements before welding, whether the tack welding is firm, and there must be no paint or rust around the weld;

[0027] 1.2) Welding current: select the appropriate welding current according to the thickness of the weldment, welding level, electrode type, diameter, welder proficiency and other factors;

[0028] 1.3) Arc ignition: The starting and landing arc point of the fillet weld should be at the end of the weld, preferably greater than 10mm, and the arc should not be struck casually. After ignition and arc ignition, the electrode should be pulled away from the weld area immediately to make the gap between the electrode and the component Keep a gap of 2 to 4mm to generate arcs; butt we...

Abstract

The invention discloses a steel structure welding technology comprising the following procedures of (1) conducting downward welding including (1.4) for welding speed, conducting constant-speed welding to guarantee even welding joint thickness and width, and better making an equi-distance (2 to 3mm) between iron water in a molten bath and slag when viewed from a surface cover, (1.5) determining welding arc length according to different welding bar types, generally requiring arc length to be invariable, acid electrode length of 3 to 4mm and basic electrode length of 2 to 3mm, (1.6) welding angles can be determined according to thickness of two welding members, welding angles including an included angle of 60 to 75 degrees between a welding bar and a welding advancing direction. When the welding members have the same thickness, the included angle between the welding bar and the welding member is 45 degrees; when the welding members do not have the same thickness, an included angle between the welding bar and a thicker welding member should be larger than an included angle between the welding bar and a thinner welding member. The steel structure welding technology further comprises a (2) step of vertical position welding. The steel structure welding technology can be simply operated, requires less experience for operators and can produce products of high quality.

Description

technical field [0001] The invention relates to a steel structure welding process. Background technique [0002] There is still some experience and technicality in the adjustment of process steps and equipment parameters in the existing steel structure welding process. For new operators, a lot of practice is needed to master the operation skills and produce high-quality good product. Contents of the invention [0003] In order to achieve the purpose of the present invention, the present invention provides a steel structure welding process that is convenient, quick and easy to operate. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions: [0005] A steel structure welding process, comprising the following steps: [0006] 1), flat welding [0007] 1.1) Clean up the weld: check whether the groove and assembly gap meet the requirements before welding, whether the tack welding is firm, a...
