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 requirements.

Major Changes.

Increase focus on LEADERSHIP…Taking ownership of Quality

Increase focus on QUALITY CULTURE…. throughout the company from Top management (Leadership) to ALL personal within the company.

The “PROCESS approach” is one of the fundamental principles of ISO 9001……Every activity is a PROCESS……. Leaders need to fully understand and promote the use of the “PROCESS APPROACH”

Addition

New section on terms and definitions ….to aid clarification of specific wording.

3.8 Process

“Set of interrelated or interacting activities that uses or transforms inputs to deliver a result.

“Note 4 to entry: PROCESSES in an organisation are generally planned and carried out under controlled conditions to ensure that intended results can be achieved”

Basically, known as a STANDARD PROCESS, where you can readily check the quality of the output.

Note 5 to entry: A PROCESS where the conformity of the resulting output cannot be readily or economically validated is frequently referred to as a “SPECIAL PROCESS”

Therefore, Leaders need to Lead to ensure QUALITY is built into ALL PROCESSES to develop an adequate QUALITY CULTURE throughout the company.

Quote from Special Process Institute Guidebook 4.1 Process Control

SPECIAL PROCESSES require a different approach to control them. Instead of the output being directly measured for conformity, the process itself is “measured” (validated). This validation process takes the form of periodic testing and qualification of the process and/or operators against criteria detailed in specifications.

There are many different SPECIAL PROCESSES used across ALL manufacturing industries………. many material JOINING PROCESSES are classified as SPECIAL PROCESSES.

All BRAZING processes are SPECIAL PROCESS…… Flame/torch brazing is a “Special process”
