While the first step in successful punching is to pay close attention to the quality and features of punching tooling, other factors come into play. Punched slugs are clues, and examining them can reveal whether the punch and die clearance is too loose or too tight and whether the machine is properly aligned.

Starting a portable GTAW business takes a lot of hard work and dedication, but it also requires some solid business knowledge before getting started. It's important to learn about what equipment you need, how to set it up, and how to evaluate your welding before you take your first job.
To prevent martensitic transformation in stainless steel during drawing operations, warm forming has been explored. In experiments, warm forming eliminated intermediate annealing operations and substantially increased limiting draw ratio values.

Contrary to common opinion, a high production rate is not the key to success in making tube. Attempting to low-ball the price — while cutting corners in maintenance and upgrades -- is a poor strategy in this industry. Columnist Bud Graham provides four production scenarios that compare various rates of capacity utilization and line speed and how these affect profitability.

Good sawing and maintenance practices can help alleviate problems that can occur when making angle cuts in structurals and tubing. Addressing the stock, machine setup, the blade, the cutting fluid, and the saw itself may not completely rid fabricators of problems, but it can help keep the operation profitable and relatively painless.

The cold mill pilgering process uses ring dies and a tapered mandrel to reduce tube cross sections by up to 90 percent. Because the process relies on large number of small forming steps, the result is tube or pipe that has nearly homogenous material characteristics. It is suitable for every metal.
