The Lead Burning Process

The lead burning process is used whenever there is a need to coat, line, or fabricate an item with lead. Sometimes referred to as “lead welding,” the lead burning process is commonly used in coordination with procedures for making repairs or when performing scheduled maintenance. In simple terms, lead burning is similar to welding with the exception that the metal being welded is lead as opposed to steel.

The list of items that lead burning is performed on is quite impressive. This includes lead floors and walls, tank linings, lead pipes, and lead support systems. As part of this process, lead can be bonded to steel. This is seen in the lining of a vessel or tank, as well as support and header systems. Lead burning may also involve copper when creating a standardized bonding lead cover or lining.

The lead burning process is used for many purposes and the most common use of lead burning is in metal smelter operations, or any place with a highly corrosive atmosphere. As a prime example, acid tanks (baths) used in metal pickling operations are lined with lead, a lining created by a qualified lead burner. When the lead burning process is complete, the joined lead alloy pieces are rigid, strong, uniform, and void of any pinholes. Using a controlled, concentrated flame, there is no risk of adjacent areas overheating.

Someone interested in becoming a lead burner, also known as a welder, is required to complete 8,000 hours of structured apprenticeship over five levels. As for testing, this is carried out at the conclusion of each level. After finishing each level, the apprentice can then move on to the next level. For confidence in the lead burning process, it is important to ask for accreditation from the lead burner.

Canada Metal North America, as Canada’s oldest lead company, has the knowledge and expertise required to handle any type of lead burning project on schedule and in an efficient and economical manner.
