Electric Resistance Welding sections and Cold Drawn tubes represent distinct forming processes for creating accurate metal products . ERW piping typically employs rapid resistance welding of sheet metal seams , resulting in a relatively less expense but potentially greater geometric inconsistencies . In comparison , Cold Drawn piping are produced through a cold drawing method that considerably improves physical exactness and surface quality , although at a greater cost point . Thus, the most suitable option depends on the specific application and the necessary degree of precision .
Precision Tube Fabrication: ER and Cold Expanded Welded Methods
Modern precision tube manufacturing relies heavily on two key technologies : Electric ER Welded ( Electric Resistance Welded ) and Cold Enlarged Welded ( Cold Expanded Welded ). Electric Resistance Welded involves forming a tube from coil material and joining the edges together using heat opposition . Cold Expanded Welded , on the other hand, refines upon the Electric Resistance Welded method by post-welding coldly stretching the tube to improve its dimensional accuracy and functional characteristics . These distinct techniques cater to a wide range of purposes, each supplying unique benefits in terms of expense, resilience , and outer finish .
