Measuring Productivity
Understanding how to effectively measure productivity is key to tracking improvement in the welding operation. It can be measured in several ways — from arc-on time to deposition rate and the number of parts out the door. Focusing on only one measure is not a recommended practice, as all three measures should be considered collectively to best understand the financial impact.
If an organization finds that its arc-on time and deposition rates are low, there are numerous common causes to consider:
• Parts not arriving at the weld cell on time
• Incorrect parts delivered to the weld cell
• Poor part fit-up that creates excessive time spent clamping fixtures and filling gaps
• Clamping fixtures that need replacing
• Inefficient weld cell layout
• Wire feeding problems
• Gas flow problems leading to contact tip burnback
• Downtime for maintenance issues, including liner changeover
• Rework of poor welds due to porosity or other issues
• Excessive time spent on post-weld cleanup or grinding

CWB Group (Canadian Welding Bureau), is dedicated to the enhancement of public safety and the success of its clients.
It is an administrator of CSA standards, a certification organization, a private, not-for-profit organization, and is funded solely by the industry from fees charged.
It is not the welding police, a branch of the government, an inspection organization, a standards-writing body (CSA does that), or an association, society, or club.
He said CWB offers a value optimizer, which is a productivity assessment tool to evaluate the productivity of a company's manufacturing operation, including welding. The Value Optimizer Assessment examines and advises on 10 key areas: workplace design; joint design; over-welding; joint preparation and fit-up; preparation methods; auxiliary equipment considerations; welding-process selection; operator efficiency; welding parameters; and use of procedures.
Pearce said the CTEA Welder Evaluation is a free evaluation service to CTEA members in which welders test with a CWB representative at the welders' facility. A “T” joint with a fillet weld is evaluated on site and a brief report is presented, including a table with the welders' names and the results.
The CWB Group includes:
The CWB Group includes:
Canadian Welding Bureau, with five regional offices across Canada: Ontario (Milton); Alberta (Edmonton); Manitoba (Winnipeg); Quebec (Lavelle); and Atlantic (Halifax).
Quasar, the group's ISO registrar offering management systems auditing services.
INTEG, offering NDE training courses for non-destructive testing.
Canadian Welding Association (CWA), a professional association for the welding industry, a not-for-profit division of the CWB Group, a national membership-driven association, and advanced Welding Technology Centre.
He said the CWB Group tests over 50,000 welders a year, and welders must be tested every two years.
