Applications and Advantages in Tank Fabrication and Maintenance
In the fabrication of storage tanks, as in most other welding applications, there are two crucial processes that storage tank fabricators must carry out to ensure the final quality and durability of the tanks. They are weld preheating and post-weld heat treatment.
Pre-Heating
Preheating involves heating the material to be welded to a particular temperature before welding. This process reduces shrinkage by minimizing the temperature between the arc and the base material. It also removes moisture, lowers hydrogen, and slows the weld cooling rate. These reduce the risk of cracking, brittle welds, and failure of the welds. Preheating is crucial for storage tanks as they are to withstand high pressures during operation.

Power is out to more than 500,000 customers with an estimated 3 to 5 weeks to restore power. Generator-powered, air conditioned tents have been set up to provide power workers with meals; and we’ve also supplied generators for power requirements for restaurants, casinos, fabrication shops, etc.
Other members of our South West Region team are working tirelessly to mobilize generators for all segments of need. A big thanks goes to Michael Stevens and all our supporting personnel to be able to deliver more than 100 generators in a matter of hours.
Special thanks goes to Dave Kendrick and his team, for their outstanding efforts preparing our Lake Charles building prior to the hurricane landing. Dave worked late into the night to provide us with the best chance of weathering the storm. In the pictures below, you can see we sustained minimal damage compared to other buildings located down the road and we are very fortunate to have come out of this storm as well as we did.
Thanks to all for a job well done!
