Abstract
The present invention belongs to the field of welding technology, and is especially welding process to form round external and internal corners. The welding process includes the first argon arc welding and the subsequent laser welding to cover the weld seam the argon arc welding forms. The said welding process can form beautiful round weld seam while ensuring the airtight of the weld seam.
Description
Technical field
The invention belongs to welding field, particularly the welding method at R angle or turning.
Background technology
Laser weld can adopt continuously or pulse laser beam is realized, the principle of laser weld can be divided into heat-conduction-type welding and Laser Deep Penetration Welding.Power density is less than 104～105W/cm
2Be heat conduction weldering, fusion penetration is shallow at this moment, speed of welding is slow; Power density is greater than 105～107W/cm
2The time, the metal surface is subjected to the recessed one-tenth of heat effect " hole ", forms deep penetration welding, has the advantages that speed of welding is fast, depth-to-width ratio is big.
But with the various sealing gas tank of laser weld the time,, be easy to generate pore, cause revealing at R angle or corner.Because of the light beam of Laser Welding is Φ 0.10mm, and do not add the packing material welding again.Produce a gradient at thickness direction after the sheet material bending in addition because in laser weld, the fusing amount of thin plate mother metal is not enough, caused the local area welding less than, so cause leakage.Solution in the past be leak more by hand argon arc welding carry out mending-leakage, like this, cause the quality of product not pass a test and outward appearance not attractive in appearance.
Summary of the invention
Technical problem to be solved by this invention is to provide the process at a kind of laser weld turning or R angle, now plate sheet welding is become various sealing gas tanks to solve, and at R angle or corner, is easy to generate the problem of leakage.
The present invention addresses the above problem by the following technical solutions.
The process at a kind of laser welding R angle, turning is characterized in that, at the R angle or corner weld earlier with argon arc welding, and then carry out Laser Welding.
Further, when carrying out argon arc welding, can add packing material.
Carry out argon arc welding earlier, guaranteed at the R angle or corner can not produce leakage.By the covering of Laser Welding, the vestige of hydrogen arc weldering just cannot see, and has both guaranteed the sealing of gas tank, makes outward appearance beautiful again, does not allow the people that the sensation of patch installing is arranged.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
The process at a kind of laser welding R angle, turning, at the R angle or corner weld earlier with argon arc welding, and then carry out Laser Welding.When carrying out argon arc welding, can add packing material.For the present invention, adopt the technological parameter of argon arc welding and Laser Welding to select for the person of ordinary skill of the art, be to select very easily, simultaneously when carrying out argon arc welding, the selection of packing material for the person of ordinary skill of the art, also be to select easily, do not do detailed description at this.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
