Details for Solderers and Brazers


Description

Braze or solder together components to assemble fabricated metal parts, using soldering iron, torch, or welding machine and flux.

Tasks

  • Examine seams for defects and rework defective joints or broken parts.
  • Align and clamp workpieces together, using rules, squares, or hand tools, or position items in fixtures, jigs, or vises.
  • Melt and apply solder along adjoining edges of workpieces to solder joints, using soldering irons, gas torches, or electric-ultrasonic equipment.
  • Clean workpieces to remove dirt or excess acid, using chemical solutions, files, wire brushes, or grinders.
  • Grind, cut, buff, or bend edges of workpieces to be joined to ensure snug fit, using power grinders and hand tools.
  • Clean joints of workpieces with wire brushes or by dipping them into cleaning solutions.
  • 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.
  • Turn valves to start flow of gases and light flames and adjust valves to obtain desired colors and sizes of flames.
  • Melt and apply solder to fill holes, indentations, or seams of fabricated metal products, using soldering equipment.
  • Heat soldering irons or workpieces to specified temperatures for soldering, using gas flames or electric current.
  • Brush flux onto joints of workpieces or dip braze rods into flux to prevent oxidation of metal.
  • Smooth soldered areas with alternate strokes of paddles and torches, leaving soldered sections slightly higher than surrounding areas for later filing.
  • Melt and separate brazed or soldered joints to remove and straighten damaged or misaligned components, using hand torches, irons, or furnaces.
  • Remove workpieces from fixtures, using tongs, and cool workpieces, using air or water.
  • Connect hoses from torches to regulator valves and cylinders of oxygen and specified gas fuels.
  • Sweat together workpieces coated with solder.
  • Dip workpieces into molten solder or place solder strips between seams and heat seams with irons to bond items together.
  • Place solder bars into containers and turn knobs to specified positions to melt solder and regulate its temperature.
  • Turn dials to set intensity and duration of ultrasonic impulses, according to work order specifications.
  • Select torch tips, flux, and brazing alloys from data charts or work orders.
  • Cut carbon electrodes to specified sizes and shapes, using cutoff saws.
  • Clean equipment parts, such as tips of soldering irons, using chemical solutions or cleaning compounds.
  • Remove workpieces from molten solder and hold parts together until color indicates that solder has set.

Interests

  • Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.

Education, training, experience

  • Education - These occupations usually require a high school diploma.
  • Training - Employees in these occupations need anywhere from a few months to one year of working with experienced employees. A recognized apprenticeship program may be associated with these occupations.
  • Experience - Some previous work-related skill, knowledge, or experience is usually needed. For example, a teller would benefit from experience working directly with the public.
