What is the difference between Soldering, Brazing, and welding?

Welding refers to the process of creating a metallurgical bond between two components by way of using high energy to melt the base components (and sometimes a filler material), forming a mixed alloy of the two base parts.

Soldering is the process of joining two components by way of melting a filler material to act as a “glue” between the parts to be joined. The “glue” is another metallic compound that has a lower melting point than the metals to be joined. At the precise temperature just above the melting point of the filler material and below that of the base materials, the filler material will flow into the voids between the carefully positioned base parts by way of a process called capillary action. When the joined assembly is removed from the heat, the filler material will solidify into a durable, airtight, joint.

Similar to a soldering process, brazing takes place at higher temperatures, typically over 450°C in order to create a joint with more strength using stronger filler materials.

Brazing can be accomplished via handheld or fixed torch in the open air, but in order to achieve the best possible brazed joint you need to remove as much oxygen as possible. This is where furnace brazing comes into play. Brazing furnaces displace the oxygen surrounding the work environment to allow for the ideal brazing conditions. Read more

What to know to find a quality lead-free parts manufacturer

Learn to look for suppliers specializing in lead-free metal products

Finding the right manufacturer for quality lead-free parts can be a challenge. It starts by assessing the quality of the part production. Lead makes a metal easier to work with, so switching to newer, lead-free alloys requires specialized skills.

A parts manufacturer must first understand how to work with the more unforgiving lead-free, or low-lead, material, and then know how to use innovative approaches to adapt the manufacturing process.

It’s like knowing how to build a standard car engine in steel – versus having the experience to create a performance engine in high-grade aluminum. You’ve got to be an expert in the material, and know your craft.

For businesses that need to find quality lead-free machined parts for potable water systems, sourcing the best supplier is essential. The goal is to find manufacturers who use careful production strategies – designed just for lead-free metals – and who can supply the highest quality parts, at competitive prices.

So, what do you look for in a lead-free products supplier?

Article Overview

In this article, you will learn answers to:

    • What exactly is a lead-free, or low-lead, metal alloy?
    • What’s involved in making quality lead-free plumbing components?
    • Why, and when, did lead-free metal become required in potable water systems?

Finally, get a Quick List of the information you need to know to search for, and source, a quality lead-free and EcoBrass® parts supplier.
