Ethan Bale

Hi, I am Ethan, the owner of this website. I have been a welding engineer for the past 8 years and found it to be an extremely interesting occupation. The world of welding is like a sea, the learning is endless. This website is an endeavor to share the insights that I acquired through the eight years of exposure to ASME Codes & Standards and welding on Coded equipment.

Welding Arc Blow: How to Minimize Magnetic Forces

by

Welding arc blow is the deflection of an electric arc from its normal path due to magnetic forces. It is mainly encountered with dc welding of magnetic materials, such as steel, iron, and nickel, but can also be encountered when welding nonmagnetic materials. It will usually adversely affect the appearance of the weld, cause excessive spatter, and … Read more

Plasma Arc Cutting (PAC)

by

The plasma arc cutting process cuts metal by melting a section of metal with a constricted arc. A high-velocity jet flow of hot ionized gas melts the metal and then removes the molten material to form a kerf. The basic arrangement for a plasma arc cutting torch, similar to the plasma arc welding torch, is shown in figure … Read more

Miller Diversion 165: Ac/Dc TIG Welder

by

Miller TIG Welder Diversion 165 AC/DC TIG Welder has an Easy-to-understand operator interface. Only three switches to operate the machine: Power switch Material selection switch Amperage control/material selection switch Inverter-based, AC/DC power source – which has very little down time – provides a consistent welding arc while operating more efficiently. Miller TIG Welder Diversion 165 AC/DC has … Read more

Arc Welding Electrode Classification System

by

The SMAW electrode classification code contains an E and three numbers, followed by a dash and either “15” or “16” (EXXX15). The E designates that the material is an electrode and the three digits indicate composition. Sometimes there are letters following the three digits; these letters indicate a modification of the standard composition. The “15” or “16” … Read more

Oxy acetylene Aluminum Welding

by

While aluminum has a melting point less than half that of steel, its conductivity is over three times as great, so we use a tip about the same size for this metal as we do for steel, and because of this conductivity, we should realize that the effects of expansion and contraction must be particularly guarded against, … Read more
