Bumba Skills Development & Projects– FREQUENTLY ASKED QUESTIONS
Q. What is welding, anyway?
A. Welding is the joining of two or more materials through heat or heat and pressure, forming a bond between them.
Q. How hot does it have to be to melt steel?
A. Steel melts at 2,800 degrees Fahrenheit.
Q. What is the most common form of welding?
A. The three most common welding processes are:
· Gas Metal Arc Welding (GMAW), which uses a consumable wire electrode. GMAW is common in high-production manufacturing
· Gas Tungsten Arc Welding (GTAW), which uses a nonconsumable tungsten electrode to make high-precision welds. GTAW is
common in the aerospace, nuclear, and food industries.
· Shielded Metal Arc Welding (SMAW), which uses flux-covered electrodes. Often called "stick" or "stick-electrode" welding, SMAW
is a frequent choice for repair and occasional welding.
Q. What is Resistance Welding?
A. Resistance Welding, uses electrical resistance and pressure to fuse metals, instead of an arc.
Q. What is the mission of the Bumba DSP?
A. To advance the science, technology, and application of welding and allied processes, including joining, brazing, soldering, cutting,
and thermal spray. for the better of South African
Q. How many welding professionals are working now?
A. Some 429,000 welding professionals currently work in the South Africa. Many are engaged in work
critical to the nation’s well-being, such as energy production, highway transportation, manufacturing, and
Q. Do I need an education to be a welder?
A. Yes. High-tech manufacturing applications using newly developed materials are creating a greater
need than ever for a highly educated workforce, and nowhere is this truer than in the field of joining and
Q. But, isn’t a lot of manufacturing moving overseas? What jobs are still available for welders
in the South Africa?
A. Many jobs for trained welders exist. Jobs that require significant technical skills, such as welding, are
expected to increase 50 percent in the next 10 years. A significant portion of the S.A. energy and
transportation infrastructure was constructed in the 1950s and 1960s. Now, 40 to 50 years later, skilled
welders are in demand to maintain and update these facilities and structures.
Q. I’m interested in a career in welding, but I’m also interested in computers. Is there any way
to combine my interests?
A. Yes. Computer skills are increasing in importance as welding professionals become responsible for
programming computer-controlled welding machines, including robots and lasers.
