Gas Welding Principles Quiz

• Gas welding is a non-pressure welding technique using high temperature flames from a mixture of oxygen and acetylene.
• Oxy-acetylene welding produces a weld by heating with a flame from oxygen and acetylene gases, melting the metal and requiring additional metal from a filler rod.
• The temperature of an oxy-acetylene flame is 3200°C, suitable for metal sheets and plates with thickness between 2 to 50 mm.
• Before welding, metal pieces' dimensions must be checked using a vernier caliper, rust removed with emery paper, and marked with a scriber.
• The welding area should be well ventilated and metal pieces may be folded using a folding machine along marking lines.

Test your knowledge on the principles of gas welding, a type of non pressure welding that uses a high temperature flame from a mixture of oxygen and acetylene to melt metal parts. Learn about the various types of non pressure welding including oxy-acetylene and oxy-hydrogen.
