Braze or solder together components to assemble fabricated metal parts, using soldering iron, torch, or welding machine and flux
- Melt and apply solder along adjoining edges of workpieces to solder joints, using soldering irons, gas torches, or electric-ultrasonic equipment.
- Heat soldering irons or workpieces to specified temperatures for soldering, using gas flames or electric current.
- Examine seams for defects and rework defective joints or broken parts.
- Melt and separate brazed or soldered joints to remove and straighten damaged or misaligned components, using hand torches, irons, or furnaces.
- Melt and apply solder to fill holes, indentations, or seams of fabricated metal products, using soldering equipment.
- Clean workpieces to remove dirt or excess acid, using chemical solutions, files, wire brushes, or grinders.
- Guide torches and rods along joints of workpieces to heat them to brazing temperature, melt braze alloys, and bond workpieces together.
- Adjust electric current and timing cycles of resistance welding machines to heat metals to bonding temperature.
- Clean equipment parts, such as tips of soldering irons, using chemical solutions or cleaning compounds.
- Turn valves to start flow of gases and light flames and adjust valves to obtain desired colors and sizes of flames.
