For the best view keep your head off to the side and out of the weld fumes to ensure youre welding in the joint and keeping the arc on the leading edge of the puddle. However some experienced welders argue that even a lifetime in the trade cannot make you an expert as no two welds are ever the same.

The aRc-weLDing ciRcuit The operators knowledge of arc welding must go beyond the arc itself.
How to learn arc welding. It was produced with a great deal of help and guidance from professional welders whose time was funded by forum members and supportersTake the tutorial slowly and practice the work covered on each page before moving onto the next. Do not let the challenge of becoming a welder deter you. If you are asking yourself how to arc weld and maintaining travel speed you simply need to keep the arc in the leading 13 of the weld pool.
Position yourself so you have a good view of the weld puddle. X Research source Stick and MIG welding equipment is cheaper and easier to learn than other methods. In the video the arc is started with a tap start.
The rod quickly becomes shorter as the weld progresses and the motion that can be seen is constant correction to maintain a short arc length. If you want to get the most out of your welding practice your knowledge of welding must go beyond the arc. By applying intense heat metal at the joint between two parts is melted and caused to intermix directly or more commonly with an intermediate molten filler metal.
Arc welding is one of several fusion processes for joining metals. The 2 most common methods for beginners are gas metal arc welding MIG and arc welding also referred to as stick welding. A tiny amount of weave can be used to help control speed and direction.
Instructors teach you to slice through metal with the hot flame of an oxyacetylene torch and to use power and hand tools to finish your work. Learning how to mig weld is fun and easy. This tutorial is intended to offer practical advice to beginner arc welders.
Adjust your welders output amperage to suit the material you are welding and the desired penetration of the arc. Intense heat is generated due to the arc produced. Upon cooling and solidification a metallurgical bond is created.
However the process is extremely slow and that why its been replaced with arc welding processes. The primary input lead is either 415 V or 240 V and should never be tampered with altered or repaired except by a licensed electrician. As the electrode is brought near the base metal 2-4 mm apart where the welding is to be done spark or arc starts to produce in between the base metal and electrode.
Apprentice welders work under the tutelage of experienced welders. You can learn welding in as little as six months by taking classes in a welder training program. Make sure your stance allows you to.
It is important for welders to understand the symbols as much as learning how to properly weld. How to Arc Weld - Tutorial. So the next best thing for beginners is the MIG welder.
How long does it take to learn welding. The output circuit of an arc welder is controlled at a safe voltage but this safe voltage can also kill if given ideal. In arc welding processes a number of potential electrocution sources can be identified.
You can open your welder put the welding wire in and be welding right out of the box. Many times they will offer specialized classes for students to learn to arc weld either as a career certification program or as workshops or classes. For most arc welding the rod is moved in a straight line to form a stringer.
Moving too slow will result in a wide convex bead. You can also learn advanced joints welding positions and techniques in arc welding and oxy-acetylene torch cutting. You also need to understand how to control the arc and this requires knowledge of the welding circuit and the equipment that provides the electric current used in the arc.
The heat produced melts the base metal electrode core or filler material in some case and flux coating. If you find the finished weld bead is pitted with deep cratering at the beads edges or the adjacent metal is simply melted or burned away reduce the amperage incrementally until the condition is corrected. Another way to learn to arc weld is through a local technical or community college.
Learn to join pieces of metal using arc welding also known as stick welding.
