How to use submerged arc flux in steel structure？

Submerged arc flux is a welding method commonly used in steel structure fabrication. Here are the steps to use submerged arc flux in steel structure welding:

Prepare the materials and equipment - You will need a welding machine, welding electrodes, flux, and shielding gas. Ensure that all equipment is clean and in good condition.

Set up the welding machine and adjust the parameters - The current, voltage, and wire speed will vary depending on the thickness of the material being welded. Consult the welding machine manual for specific instructions.

Clean and prepare the joint - Remove any rust, oil, or debris from the joint area. Use a wire brush or grinder to clean the surface.

Align the materials to be welded - Position the materials in the correct alignment and tack weld them to hold them in place.

Apply flux - The flux is a mixture of chemicals and minerals that helps protect the weld pool from contamination. The flux is applied to the weld joint using a hopper or feeder.

Begin welding - With the equipment set and the joint prepared, begin welding the joint. The operator must keep the electrode tip perpendicular to the joint and move the welding torch at a consistent speed. The flux will melt, and the wire electrode will deposit molten metal onto the joint.

Monitor the weld - Ensure that the weld pool is consistent and free from defects. If any problems occur, adjust the parameters or clean the joint and remove any contaminants.

Complete the weld - Once the weld is complete, remove any excess flux and clean the weld area to remove any debris.

Following these steps, the use of submerged arc flux in steel structure welding can produce high-quality and strong welds for various steel structures.
