THREAD CUTTING 2 - Practice Mode
1) Calculate pitch diameter of M16 x 2 mm square thread?
Explanation:
The two most common shielding gases for Flux-cored arc welding (FCAW) is a mix of 75 percent argon and 25 percent CO2.
2) Calculate the pitch diameter of M 36 x 4 mm square thread?
Explanation:
Flux cored arc welding (FCAW) is a semi-automatic arc welding process that is similar to metal active gas (MAG) welding. FCAW uses a continuous wire fed electrode, a constant-voltage welding power supply, and similar equipment to MAG welding.
There are two basic process variants; self shielded FCAW (without shielding gas) and gas shielded FCAW (with shielding gas). The difference in the two is due to different fluxing agents in the consumables, which provide different benefits to the user.
3) Calculate the pitch diameter of M 64 x 6 mm square thread?
Explanation:
Tubular cored flux electrode provides protective slag in flux cored arc welding.
4) What is the relation between pitch and lead in multistart thread?
Explanation:
A welding helmet, commonly referred to as a “hood,” is one of the most important pieces of personal protective equipment that a welder must have. An adequate helmet protects the eyes and skin not only from severe sparks, but also from potentially vision-damaging ultraviolet and infrared rays emitted by the arc.
Helmet with filtered colour glass is used to protect face from UV and Infra-red radiation during welding.
5) Find the lead of a 2 start thread having pitch 1.5 mm?
Explanation:
Leather gloves is used as personnel protective equipment (PPE) to protect hand from burning injury.
