Abstract
The invention discloses a welding process for the short cracks of an automobile frame. The welding process comprises the following steps of: a, drilling crack-arresting holes in the tail ends of the cracks; b, opening welding repair grooves along the cracks; c, welding; d, polishing and smoothing the welding repair surface. The welding process disclosed by the invention has the characteristics of simple steps, convenient operation, safety and reliability, good stability, good forming, no defects of air vent recess and the like, and guarantee on welding quality.
Description
Technical field
The present invention relates to vehicle frame and repair field, be specifically related to a kind of welding procedure of vehicle frame short crack.
Background technology
Vehicle frame is the main bearing part of automobile, conventionally bear irregular alternation repeated load, the damage of vehicle frame is mainly fatigue damage, its principal mode is fracture, and fatigue crack originates from the edge of longeron or crossbeam, when finding longeron or crossbeam cracking, should repair early, Crack prevention expansion, increases and repairs difficulty, even causes the damage of correlated parts.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of welding procedure of vehicle frame short crack is provided.
The technical scheme that the present invention adopted is for achieving the above object: the welding procedure of vehicle frame short crack, comprises the following steps: a, at the end of crackle, bore stop hole; B, along crackle, snap and repair groove; C, welding; D, be polished flat trimming weldering surface.
The angle of described repair welding groove is 90 °, and limit, slope is for repairing 2/3 of cantilever thickness.
Use emery wheel or the file repair welding surface that polishes flat.
Feature of the present invention is: step is simple, easy to operate, safe and reliable, good stability, and moulding is good, there is no the defects such as pore depression, guarantees welding quality.
The specific embodiment
The welding procedure of vehicle frame short crack of the present invention, comprises the following steps: a, at the end of crackle, bore the stop hole of Φ 5mm, to eliminate stress; B, along crackle, snap and repair groove, the angle of described repair welding groove is 90 °, and limit, slope is for repairing 2/3 of cantilever thickness; C, weld, built-up welding height should exceed plane 1-2mm; D, postwelding are used emery wheel or the file repair welding surface that polishes flat, and guarantee that weld seam rigidity is basically identical, to reduce the stress on repair welding surface, concentrate.
The above; it is only the preferably specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; according to technical scheme of the present invention and inventive concept thereof, be equal to replacement or changed, within all should being encompassed in protection scope of the present invention.
Claims (3)
1. the welding procedure of vehicle frame short crack, is characterized in that: comprise the following steps: a, at the end of crackle, bore stop hole; B, along crackle, snap and repair groove; C, welding; D, be polished flat trimming weldering surface.
