The answer is yes. You must first make sure of the following: There is no gas left in the system(probably not since most likely you are fixing a leak) That if for example you are welding a line by the evaporator the valves at the condenser have the manifold gauges connected and open to atmosphere. This way the pressure created by the heat will exhaust out the manifold gauges. If not done so the pressure will back up and out of the hole that you are trying to fix and will not allow the weld to cool and seal. Clean the area to be welded thouroughly Use silver rod to weld AC pipes and not soldering wire. The weld will be much stronger and last longer

How do you weld 6010?
6010 is a high cellulose sodium based electrode, which can be used to weld carbon steel pipes.
What is girth weld?
circumfrencial weld is sometimes referred to as Girth weld. its just another term.
What is the first weld called When using 2 pipes with beveled edges are to be welded.?
The first weld made when joining two pipes with beveled edges is called the "root pass." This initial weld establishes a foundational joint at the root of the bevel, ensuring proper penetration and alignment of the joint before subsequent layers or passes are added. It is crucial for the strength and integrity of the overall weld.
What type of joints can be used for GI pipes?
Threading joint, weld joint, Flanges joint
How do they build oil pipelines under the ocean?
Pipelines are built under the ocean with machines that have arms. These arms put the pipes into place on the ocean floor. Divers then weld the pipes together. The weight of the pipes will settle into place.
Is it possible to mig weld pipes?
Yes, but, it isn't particularly easy. You should practice on flat stock first.
What is the difference between a Butt weld and a socket weld?
A butt weld is where the diameter of the pipes welded together are the same, a socket weld is where a larger diameter pipe is fitted into a smaller one. In making a butt weld, the pipes (or pipe and fitting) usually have an angle machined or ground into the outside corner, so when they are placed together face-face, there is a circumferential V shaped gap serving as the weld prep. In a socket weld, the pipe is inserted into the socket, backed off slightly to make a gap between the end of the pipe and the bottom of the socket, and the weld is made around the outside diameter of the socket to the outside diameter of the pipe. The gap at the bottom of the pipe prevents thermal expansion from stressing the joint during or after welding.
What is the process for joining ABS pipes using solvent weld?
To join ABS pipes using solvent weld, you need to first clean and dry the pipe ends. Then, apply ABS cement to both the pipe ends and the fitting, and quickly push them together. Hold the joint in place for a few seconds to allow the cement to set. This creates a strong, permanent bond between the pipes.
How do you stop pipes from bending when welding?
Metal expands as it is heated and contracts as it cools. Keeping the heat input even, completely around the pipe, will help. If possible reheating the weld area after the weld is complete can help to "stress relieve" the joint. Using a weld "fixture" to prevent bending is another possibility.
What is circumferential welding?
A type of weld produced around the outer surface of a cylindrical workpiece. Circumferential welds are used to fabricate structural pipes
The two types of welds are?
TIG uses tungsten in a gun and electricity to melt the material, the user must manually add filler rod. Needs shielding gas Mig uses a gun, but the filler rod flows out of the gun. Electricity flows from tip of wire into material. needs shielding gas except with flux-cored wire. SMAW uses pre fluxed electrodes. electricity flows trough electrode holder, into material when material is scraped by electrode. No shielding gas. Oxy-fuel. Flame welding. Oxygen and a fuel (acetylene, propane, mapp, etc.) are mixed in a torch, ignited, and used to melt material. filler wire is manually added. There are more indepth explanations, and advanced machines, but that is the basics.
