6. Mistakes to avoid

6.1 Don't think that hot nitrogen welding is a luxury

No, weld protection is not a luxury; it really does enable gains by :

• simple design and guaranteed assembly success;

• production, a saving in joint material and time (compared to hot plate welding);

• in production, operators and set-up personnel can rest easy knowing that variations in the shape and dimensions of parts are absorbed;

• quality control, incomparable weld uniformity, in the event of machine drifts; these are easily detected during production.
