Flame Brazing

Are you currently using FLAME / TORCH brazing in your process?

Are you considering FLAME / TORCH for a new process?

If the answer is YES whether your requirement's are for manual OR mechanized flame brazing, then this web site is dedicated to you.

A flame is a heat source….the purpose of the flame is to raise the temperature of the material it touches to a sufficiently high enough temperature to enable a process to be carried out…what is the process? And what type of flame is required?

One such process is Flame Brazing (often referred to as Torch Brazing).

Brazing is a time/temperature process where the flame is the source of the temperature.

There are many other factors (apart from the nature and composition of the flame) that must be considered in order to carry out a flame brazing process successfully. 


The objective of the end user who is carrying out the flame brazing operation is to make leak tight joints that pass what ever quality requirements their customer or customers customer specify. 

Some simple questions;

Joint cleanliness……”How clean is clean?”

Joint design…………”How near best practice is the joint design and tolerances?”

Uniform Heating……”How uniform is the heating of the joint?”

Leak testing…………”How leak tight is leak tight?”

Process………………”How do you control the process?”

Process………………”How repeatable is the process?

There is probably scope to improve most flame brazing applications………But to what cost/benefit?

We look forward to discussing your requirments.

Do I need new equipment?

FLAME BRAZING done well isn't the result of buying the most expensive equipment.

Often the equipment may be 'fit for purpose' - the problem is that the equipment may not be being used to its full potential.

That's a view expressed by Derek Davies who has trained and written about the Flame Brazing process for over 30 years.

"I always say that the equipment is the last thing to think about, not the first – the first is getting to understand the customer's process and objectives and then determining what equipment best fit his needs, " says Derek.

He added: "It might be what I can build and supply, it might be a more automated machine, in which case I will direct them to a machine builder, but the process has to be developed first, the potential customer does not always understand what equipment is available."

Derek uses a 0-10 complexity scale to help his customers understand the best way forward in improving their Flame Brazing operations.

According to Derek, all flame brazing processes and equipment lies somewhere on the simple complexity scale between  0-10 as follows:

0 - simple manual flame process using a hand held torch
1 - simple bench mounted flames
2-3 simple small shuttle brazing machines.
4-5 more complex small shuttle machines
6-8 more complex rotary or in-line machines
8-10 extremely complex automatic machines

Says Derek: "The customer might already have some flame brazing machine/ equipment and have problems, in which case an option for him is pay for my services to audit his brazing process and get down to the route causes of him brazing issues."

In this way, Derek can diagnose problems for the client without the client having to re-tool or re-train, saving clients a lot of money and heartache in the process.

"Sometimes the source of the problems quite often are the component, design, fit up or cleanliness," added Derek.
