The term component cleaning leaves out the cleaning of steel sections and sheets, and finally, degreasing only describes a part of the topic, as in most cases, chips, fines, particles, salts, etc. also have to be ...
However, these same properties, combined with the lack of traditional gum adhesive, make tape removal, if needed, quick, clean, and easy. Another form of self-amalgamating tape is made from ethylene propylene rubber (EPR) and has similar uses as silicone self-amalgamating tape but is non-vulcanising and has good moisture resistance. It is ...
Prior to painting, it is desirable to "feather" or taper any edges between metal and old paint. [5] It is also important to check the surface for any oil deposited during chipping, and if necessary, to clean the area with solvents.

Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.
High-quality brazed joints require that parts be closely fitted with base metal surfaces exceptionally clean and free of oxides. In most cases, joint clearances of 0.03 to 0.08 mm (0.0012 to 0.0031 in) are recommended for the best capillary action and joint strength; [ 6 ] in some brazing operations, however, it is not uncommon to have joint ...
