When MIG welding STEEL a mixture of Argon -- CO2 is used. 75% - 25%
ER70S-6 is a very common filler metal when welding with Gas Metal Arc Welding or Gas Tungsten Arc Welding on a low carbon steel (mild steel). This can be purchased as a spool or in rod form.
A Welding Procedure Specification (WPS) is a document that provides variables and conditions of a welding procedure that is produced for a very specific application. To write one properly, experimentation and calculations must be done to find the correct parameters for the procedure. To generalize, a WPS must include all known parameters of the process; including process type, current, current type, voltage, shielding gas type, shielding gas flow rate, base metal, electrode type and size, filler metal type and size, joint design, and travel speed. There may be more variables than listed, depending on the application. One must also remember that on a WPS, ranges for variables are used that are adjustable by the welder or welding operator. Ex. Current (Amperage) 150-170 A instead of just saying 155 A. To find these ranges is where calculations are necessary.
The percentage of time a welding machine can be used continuously is typically referred to as its duty cycle, which is often expressed as a percentage over a 10-minute period. For example, a machine with a 60% duty cycle can be used for 6 minutes of welding followed by 4 minutes of cooling. Duty cycles vary based on the type of welding machine and its specifications, with common values ranging from 20% to 100%. Always refer to the manufacturer's guidelines for the specific duty cycle of a given machine.
carburizing flame is used
It's called Fusion Welding. You answered your own question.
Most cutting and welding is done with a neutral flame.
Depends on the type of material to be welded, the size of the flame, and in my situation slowly deteriorating eyesight. Basically shade 4 or 5 will be adequate. As dark as 6 on aluminum. You will be able to tell if you aren't using a dark enough shade as you can get a "flash" ( Like a sunburn on the eyes). Start with a #5 and go from there.
A gas flame in welding can reach temperatures ranging from 3,000°F to 6,300°F (1,649°C to 3,482°C) depending on the type of welding process and gases used. These high temperatures are necessary to melt and fuse metal together during the welding process.
"While using welding equipment, you should always wear safety googles and protective gloves." Make sure you have on a welding jacket and long pants when you're using welding equipment. Those sparks can be very dangerous.
What type of welding can we use LPG ?
An oxyacetylene flame is a type of hot, precise flame created by combining oxygen and acetylene gases in a welding torch. This flame is commonly used in metal cutting, welding, and brazing applications due to its high temperature and ability to produce a concentrated heat source.
Transformer type welding machine
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
The roaring blue flame is typically used for high-heat applications, such as in welding, brazing, or certain types of metalworking. It indicates a complete combustion of gas, providing a hotter and more efficient flame. This type of flame is ideal for tasks requiring precision and intense heat, as it helps achieve faster melting or joining of metals. Always ensure proper safety measures are in place when using high-temperature flames.
