Background technique
Welding wire is a kind of as filling metal or the welding material as conductive wire simultaneously.In its manufacture processing
When, surface can have many grease stains, cause the surface of welding wire very dirty.Therefore, butt welding silk table is generally required before use
Face is cleaned.
Since the surface of welding wire does not coat the solder flux of anti-oxidation effect, plastic bag sealing packaging is generallyd use, therefore every
It should be finished as early as possible behind Kaifeng, the welding wire otherwise polluted is difficult to use again.For carbon steel welding wire, aluminium alloy welding wire, magnesium alloy solder wire
For, when its location mode is improper or stores for a long time, surface gets rusty easily, when welding can be generated in weld seam stomata with
Slag inclusion, so that welding quality causes adverse effect.
Traditional welding wire surface cleaning method is carried out using chemical agent or mechanical means mostly.Chemical agent cleans ratio
It is relatively inexpensive, but there is the problem of cleaning waste liquid is difficult to handle, easily causes environmental pollution；There are take when cleaning charge for mechanical means

Put the problem in face of those skilled in the art.
Laser cleaning technique is considered as a kind of most reliable, most effective " green " cleaning method, it is close using high power
Degree laser beam irradiates the surface of object to be cleaned, makes pollutant or oxide layer on surface that flash evapn, rupture or stripping occur
From thus achieving the purpose that surface clean.But at present it is not yet found that close welding wire surface dirt laser cleaning method in terms of report
Road.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of welding wire surface dirt laser cleaning methods.
In order to achieve the above object, welding wire surface dirt laser cleaning method provided by the invention includes carrying out in order
The following steps:
1) optical-fiber laser washer is prepared, the optical-fiber laser washer includes laser, optical fiber and cleaning head；Wherein
Laser connects cleaning head by optical fiber；Cleaning head is annular in shape, and circumferentially spaced distance is formed with multiple on inner peripheral surface
Radiating laser beams mouth；
2) according to the material and size of welding wire to be cleaned, the technological parameter of laser on optical-fiber laser washer is adjusted；
3) welding wire to be cleaned being wrapped in wire-feed motor dish axle is made at the uniform velocity to pass through the axial centre of cleaning head；At the same time,
Laser beam is issued using laser, is transferred into cleaning head by optical fiber, it is then to be cleaned from multiple radiating laser beams opening's edges
The radial direction of welding wire is incident on the surface of welding wire to be cleaned, thus cleans to dirt thereon, and the welding wire after cleaning can be straight
It connects for welding.
In step 1), the laser uses optical fiber laser, and light extraction mode is pulse mode.
In step 2), the technological parameter of the laser is as follows:
Power: 10~100W；
Frequency: 50~80KHz；
Cleaning speed: 30~100mm/s；
Wash number: 1~3 time.
In step 3), the welding wire to be cleaned is one of carbon steel welding wire, aluminium alloy welding wire and magnesium alloy solder wire.
Welding wire surface dirt laser cleaning method provided by the invention has the advantages that
Process and easy to operate, easily operated implementation, and do not use any hazardous chemicals.This cleaning method
It can replace traditional chemical agent cleaning and mechanical grinding cleaning, and the welding wire surface after cleaning is smooth, bright, clean.
