Embodiment Construction

[0018] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] The invention provides a nickel-based alloy surfacing welding process for alloy grooves, see for details figure 1 The difference between it and the prior art is that the welding process is carried out by cold metal transition welding, and the welding process uses molten electrode gas for shielded welding. The specific welding process steps are as follows: a, preparation before welding, firstly treat the cylinder head alloy groove Carry out the first cutting treatment on the welding surface, then clean t...

Abstract

The invention relates to a nickel-based alloy surfacing welding process for an alloy tank. A welding process is carried out by way of cold metal transition welding, and shielded welding is carried outby adopting consumable electrode gas in the welding process. During use, the dilution rate of the surface of the surfacing is reduced greatly, the high-temperature resistance and the corrosion resistance of a material are improved and a welding material is saved by adopting the nickel-based alloy surfacing welding process by way of cold metal transition welding. Meanwhile, a multi-pass surfacingmode with at least two passes is adopted in the welding process to fill the alloy tank, so that the welding defects of incomplete fusion, solder skips and the like during welding can be solved, and the welding quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of welding technology, in particular to a nickel-based alloy surfacing welding process for alloy grooves, in particular to a nickel-based alloy surfacing welding process for low-speed diesel cylinder head alloy grooves. Background technique [0002] The specific position of the cylinder head of the low-speed diesel engine is often in a state of high temperature and strong corrosion, so it is slotted during production, and the surface is surfacing with various nickel-based alloy materials with good performance to improve the high temperature resistance and corrosion resistance of this position. . In order to ensure the performance of this position, the dilution rate must be strictly controlled, that is, to increase the content of the nickel-based alloy material and reduce the content of the base metal. At present, welding is mainly carried out manually or by a combination of automatic and manual methods. It ...
