Cleaning welding slag from photovoltaic bracket
Laser cleaning is used to remove by-products formed around weld beads after arc welding. The effect of laser parameters on the removal of by-products is investigated. As laser power increases, the heat tint and oxide layer on the surface is significantly reduced.

The utility model relates to photovoltaic framves, it is intended to provide a kind of auxiliary cleaning structure for photovoltaic bracket, its key points of the technical solution are.
SAW is a unique welding method since it involves the arc which is completely submerged under the layer of granular flux. During welding, this flux that contains lime, SiO 2, MnO, CaF 2 and other compounds reacts with the contaminants in the molten weld metal and forms slag. Thus, slag is considered as waste material.
An ultrasonic cleaner (GT SONIC-P2, Guangdong GT Ultrasonic Industrial Co., Ltd.) was used for ultrasonic cleaning of the solar cells at room temperature, with cleaning frequency of 40 kHz, cleaning time of 10 min, and stirring rate of 100 r/min.
In the past, slag removal required manual labor using a chipping hammer, which was time-consuming and required a high level of physical exertion. To overcome these problems, the paragraph suggests the use of an alternative technique-an efficient slag removal machine with a simple construction.
6 FAQs about [Cleaning welding slag from photovoltaic bracket]
Can steel slag be used to produce submerged arc welding flux?
Abstract The slag generated by the steel plant has been utilized to produce submerged arc welding flux. The flux produced by recycling steel slag has been applied in the submerged arc welding process.
Can recycled steel slag be used in submerged arc welding?
The flux produced by recycling steel slag has been applied in the submerged arc welding process. The effects of recycled slag on the chemical composition, microhardness,and microstructure of weld metalhavebeenevaluated.For chemicalcomposition,weld padswere preparedand beads on plates for bead geometry were deposited.
How do you clean a slag arc?
Clean the joint from any surface impurities such as rust, mill scale, paint, or coatings, for instance, galvanized steel. Clean the slag left from previous beads because it’s not certain that the arc will burn all of them. After you use a chipping hammer on the slag, remove the remaining with a wire brush.
Does laser cleaning remove slag from a weld bead?
In the same procedure, the amount of removal on slag formed around the weld bead, which is the second group, is investigated. The specimen used in the laser cleaning was SPFH590. It was a structural steel plate for automobiles. Also, it was mainly used for automobile frames because of its excellent weldability and formability.
Why is slag considered a waste material?
SAW is a unique welding method since it involves the arc which is completely submerged under the layer of granular flux. During welding, this flux that contains lime, SiO 2, MnO, CaF 2 and other compounds reacts with the contaminants in the molten weld metal and forms slag. Thus, slag is considered as waste material.
What is the difference between reclaimed slag & recycled flux Weld?
So, welding performed with pure slag yields inferior quality weld as compare to reclaimed slag and virgin flux. Whereas welding with recycled slag yields better results with neither apparent cuts nor the porosity. These results are in similarity with fresh flux weld.
