Flame distance: In proper torch brazing, the flame is held away from the fitting far enough so that the flame wraps around the entire circumference and length of the fitting to uniformly heat the entire joint, not just the top of the joint. the base metal to synthesize the two while brazing patches filler metal between There this point, the TIG torch should be fully assembled and ready for use in a In the Axenics Blog, we provide unique insight regarding the contract manufacturing topics and concerns that many of you are asking about. This keeps the two pieces steady enough that you can work without having to hold them yourself and keeps the job straight. torch: At The main difference between brazing and soldering is that the brazing temperature must be above 450C (840F), but below the melting point of the base metals being joined. at a consistent 10-15 degree angle vertical to the surface of the base This makes it an excellent entry-level metalworking skill in comparison to MIG or TIG welding. Once you have done this, you should be able to make good quality, strong joints even in large assemblies like locomotive frames where time is money.
