How does the submerged arc welding process work?


How does the submerged arc welding process work?

In the submerged arc welding process the flux-covered electrode is replaced by the granular flux and a bare electrode. An arc between the electrode and job is the source of the heat and remains buried under a blanket of flux. This flux keeps the atmospheric contamination away. The process may be automatic or semi-automatic.See all results for this questionsp.info Can a welder fabricate an oil storage tank?Due to the difficulty of finding and qualifying experienced welders to fabricate oil storage tanks, automated welding processes will be key to meeting the demand for bulk oil storage. Orbital welding processes can help manufacturers welding oil storage tanks meet the sudden demand and enhance producers’ storage capacity in the future.See all results for this questionsp.info How is the shielding gas used in arc welding?Because the metals react chemically to oxygen and nitrogen in the air when heated to high temperatures by the arc, a protective shielding gas or slag is used to minimise the contact of the molten metal with the air. Once cooled, the molten metals solidify to form a metallurgical bond.See all results for this questionsp.info Submerged arc automatic girth seam welding machine for ...Welding plate width: For first / top shell - Min. 800mm For subsequent shells - No restriction.
