Abstract
The invention discloses a special steel welding process, and relates to the technical field of steel welding. The welding process comprises the following steps: on the basis of the original welding process which comprises welding preheating, welded junction preheating, surfacing, postwelding thermal insulation, and post weld heat treatment, without changing the original welding process, adding the following steps in the surfacing process: surfacing for 3 mm every time, locally heating the weld joint to 950-1000 DEG C, utilizing a hammer to strike the heated area to enable the area to be obviously deformed, then performing surfacing continuously, heating and striking, when the surfacing is finished, locally heating the weld joint to 880-920 DEG C, keeping the heat until cooling. According to the special steel welding process, on the basis of the original welding process, the operation process is improved to enable the welding performance to reach the ideal condition, the special steel welding process can be applied to special steel welding, parts with large partial welding amount, and parts processed with quenching, tempering and other special thermal treatment.
Description
Technical field
The present invention relates to welded steel technical field, be specifically related to a kind of special steel material welding procedure.
Background technology
China's rolling shapes are many, and all steel all can weld in principle.Different welding materials and welding procedure is had for different steel.Welding procedure comprises wlding preheating, weld bond preheating, built-up welding mode and technique, postweld heat preservation, post weld heat treatment.Common process is little for the good steel of welding performance, welding scope, or better through the part process adaptability of normalized treatment.But for the steel that welding performance is poor, the part that local welding amount is larger, or through the part through special thermal treatment such as quenching+tempering, welding risk is comparatively large, and weld seam or the body connected with weld seam very easily crack.
Summary of the invention
The object of this invention is to provide a kind of special steel material welding procedure, it is on original welding procedure basis, by operation improving technique, make welding performance reach perfect condition, and special steel material welding, the large part of local welding amount and the part through special thermal treatment techniques such as quenching+temperings can be applicable to.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: its welding procedure is: it is on original welding procedure basis, namely preheating, weld bond preheating, built-up welding mode and technique, postweld heat preservation, post weld heat treatment is welded, do not change original technique to form, increase in weld deposit process: every built-up welding 3mm, weld seam is locally heated to 950-1000 DEG C, knocking heating region with hammer makes it obviously be out of shape, continue built-up welding → heat → knock again, after built-up welding completes, weld seam is locally heated to 880-920 DEG C, and insulation is until cooling.
The present invention has following beneficial effect: it is on original welding procedure basis, by operation improving technique, make welding performance reach perfect condition, and special steel material welding, the large part of local welding amount and the part through special thermal treatment techniques such as quenching+temperings can be applicable to.
Detailed description of the invention:
