What is the difference between oxy-acet welding and lpg welding?
The Oxy-acetylene flame is much hotter and the preferred combination for the welder especially when welding pipe and plate metal. Somewhat of a rare welding procedure in modern times. Replaced by arc welding. Liquid Propane Gas burns cooler and is preferred by employers as it is cheaper. Not bad results on light gauge material, again takes longer to heat up. -RedSeal Welder
Can metallic bonds be formed from a welded joint?
Yes, welding of metals typically involves heating and fusion in resistance welding, arc welding, acetylene torch welding. Metallic bonds are formed between the substrate and the weld. The composition of the weld and the substrate around the weld inevitably is different from the material being welded.
Why is argon used in whelding?
Argon is used in welding as a shielding gas to protect the weld area from atmospheric gases such as oxygen and nitrogen. It helps prevent oxidation and enhances the quality of the weld by creating a stable arc and reducing spatter. Additionally, argon is chemically inert, which makes it suitable for a wide range of welding applications.
What is the gas for welding?
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
What argon is with metal?
Argon is an inert gas. this is not the correct answer Nor was it complete. Argon is used in welding to shield the heated metal from oxidation. This is called TIG welding, which stands for Through Inert Gas. Argon does not react directly with the metal.
What is the difference between Tig weld vs plasma weld?
When we are using the tig welder we getting welding defects on our blanks, but when using the plasma weld no defects are found
What is the difference between ultrasonic welding and radio frequency welding?
what is the difference between ultrasonic welding & radiographic welding
What is difference between preheat and interpass temperature in welding?
The prehaet temperature is taken before welding starts. The interpass temperature is taken between welding passes.
What is the difference between backhand welding and forehand welding?
back hand welding is when you pull the welding rod or whatever it is that you are using and forehand is when you push it ahead
What is the difference between a an automotive welding engineer and just a welding engineer?
"Automotive" means that such a person is specialized in cars.
What is the difference between arc welding and resistance welding?
in arc welding only heat is used to weld metal. but in resistance welding pressure will also be used along with heat.
Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
What is Difference between arc welding and gas welding?
There's some information on welding at http://www.WeldingFun.com .. should have the answer your looking for. Sorry for being to lazy to look it up
What is the difference between the SMAW and GTAW?
The main difference between these two types of welding is that GTAW uses gases to create the weld whilst SMAW uses an an electrical current. Both are very popular welding processes.
What is the difference between gas welding goggles and arc welding goggles?
If by gas welding you mean-oxyacetylene welding. The difference is just that arc welding requires a darker shade of lens. When oxyfuel gas welding (OFW) usually a shade 5 lens is recommended. When arc welding, a minimum of shade 10 lens should be used (actually shade should be determined by amount of current used).
What is the welding defects for MIG welding?
You can find pretty much all welding defects in Mig welding. There are some that are morelikely to appear than others but that is depending on the gas and power range that is being applied. The defects are: porosity, incomplete penetration (mostly in case of short circuit transfer) undercut, excessive concavity/convexity (incorrect amperage/voltage ratio), cracks (cold and hot) incomplete fusion (wrong torch angles), cold lap.
What is the difference between shielded and unshielded welding?
Shielded welding needs a gas to shield the weld from the atmoshere air. Unshielded uses a flux the burns when welding to shield the weld from the atmoshere air.
