6 FAQs about [Does the photovoltaic bracket need spot welding ]
What is solar photovoltaic bracket?
Solar photovoltaic bracket is a special bracket designed for placing, installing and fixing solar panels in solar photovoltaic power generation systems. The general materials are aluminum alloy, carbon steel and stainless steel. The related products of the solar support system are made of carbon steel and stainless steel.
What types of solar photovoltaic brackets are used in China?
At present, the solar photovoltaic brackets commonly used in China are divided into three types: concrete brackets, steel brackets and aluminum alloy brackets. Concrete supports are mainly used in large-scale photovoltaic power stations. Because of their self-weight, they can only be placed in the field and in areas with good foundations.
How to choose spot welding process parameters?
1.2 Selection of Spot Welding Process Parameters. Usually, the selection of spot welding process parameters is based on the material and thickness of the workpiece, with reference to the welding conditions table for that particular material. First, determine the shape and size of the electrode end face.
Is single-pulse spot welding recommended?
Therefore, single-pulse spot welding is not recommended. The main problems during welding are as follows: (1) The surface is easily damaged, losing the original function of the coating. (2) The electrode easily adheres to the coating, shortening its lifespan.
How much power does a spot welding machine need?
⑤ Large welding machine power is needed. The most prominent issues are the high power of the welding machine and the large electrode consumption. Generally, for spot welding of low carbon steel plates with a thickness greater than 5mm, a power of more than 200KVA is required, and the supplied electrode pressure and current are very large.
What makes a good weld spot?
Quality weld spots, both externally and internally, should have no defects. Externally, weld spots should be round and smooth, free of burns, deep indentations, and various other defects. Internally, there should be an appropriately sized, densely cast weld nugget that does not contain defects such as shrinkage holes, looseness, or cracks.
