Aluminium Flame Brazing Basics Part 1 Aluminium Brazing

Aluminium Flame Brazing Basics Part 1. Flame brazing of aluminum is not new. In fact the very first brazed aluminum assemblies were produced using a chloride based flux and a flame as the heat source. What has changed over the years is the sophistication of the types of fluxes available and to a certain extent the alloy selection.

Welding: Hazardous fume from cutting metals HSE

Most laser cutting has preprogrammed computer numerical control with the operator at a distance from the fume source. flame cutting, also known as torch or oxygengas cutting, is a chemical reaction between pure oxygen and steel to form iron oxide. It is rapid, controlled rusting. Only lowcarbon steel and some low alloys can be cut.

Flame Cutting vs. Plasma Cutting for Stainless Steel and Aluminum

In oxyfuel cutting, the flame is not intended to melt the metal, but rather is supposed to bring the material to its ignition temperature. Then, a stream of oxygen is aimed at the metal and cuts through it, creating a metal oxide slag. As a quick comparison, a common propane/air flame burns at about 3,590F, a propane/oxygen flame burns at about 4,087F, an oxyhydrogen flame burns at 5,072.

What is Flame Cutting

The process can cut from sheet metal thicknesses to 100 inch material. Prior to 1958, when Plasma was introduced, all thicknesses were flame cut. Today metal thinner than 3/81/2 are typically only cut by plasma or laser, as thin materials are very challenging to flame cut. Thin material requires a very intense preheat as the cutting speed required for a good quality cut is very high.
