stop weld and off the machine call the head staff
Alpha radiation is emitted from the amercium button in a smoke detector. When smoke goes into the smoke detector it blocks the stream of alpha particles emitted from the americium. That triggers an alarm.

Welding smoke is typically loaded with metal fumes. If you are welding mild steel, the fumes are not that bad because iron is not particularly toxic. Welding chrome or stainless steel can release some fairly dangerous fumes such as nickel and hexavalent chromium. Using an appropriate respirator or getting sufficient ventilation can provide protection.
Check your car smoke system.
Any type of smoke, steam or particles denser than air will set off a smoke alarm. This means that smoke emitted from the incense will set off a smoke alarm when in range of the detector.
I wouldn't recommend it. The smoke that is created by the welding process is beneficial to the weld but contains elements that can damage the lungs. Look for training in another trade for your health.
Exhaled mainstream smoke and sidestream smoke combined is referred to as secondhand smoke. This form of smoke is a mixture of the exhaled smoke from a smoker and the smoke emitted directly from a burning cigarette. Exposure to secondhand smoke can have harmful health effects on non-smokers.

Gas heating does not produce any "smoke" at all. Wood burning, however, produces smoke which is much more toxic than tobacco secondhand smoke. It is best to completely avoid wood heating.
