The effects tend to be shortlived. Gases and fine particles in welding fume can cause dryness of the throat coughing or tightness in the chest.
The only problem with the exhaust was the proximity of the welding shop.

Brass Galvanized coatings. Effects of welding on stainless steel By - Date 01-14-2002 1759 While Austenitic SSteels are essentially quite easily welded there are a number of issues when welding these materials. One of these issues is that one tends to get grain growth.
Is welding stainless steel difficult. Stainless steel retains heat very efficiently which makes welding it a bit more difficult especially for the novice welder. When faced with excessive welding heat stainless steel can warp from the high temperatures and even distort during the cooling process.
It can also be very unforgiving aesthetically as it displays every blemish and scratch mark thats left. Gases and fine particles in welding fume can cause dryness of the throat coughing or tightness in the chest. The effects tend to be shortlived.
Ozone in particular can cause this when tungsten. The client agreed that this was a valid concern and wanted to reduce exposure immediately. I recommended local ventilation exhaust as a means of drawing the contaminated air away from the operators.
The only problem with the exhaust was the proximity of the welding shop. The facility was also leased and he was not permitted to install duct-work. I looked at several options for this client and the.
The production of these elements occurring in stainless steel welding fume is believed to have serious effects on the health of welders and people in the welding environment. CrVI fume is highly toxic and can damage the eyes skin nose throat and lungs and is carcinogenic. If the stainless steel surface is not significantly damaged the passive layer will likely restore itself naturally when a new reaction between chromium and oxygen particles occurs.
However various industrial processes such as cutting grinding and welding can irreversibly destroy the protective layer on the steel surface. However welding is loud enough to cause minor nerve cell damage and minor damage on a daily basis adds up over the years. Even moderately loud noise such as that produced by welding leaves auditory nerve cells affected permanently.
Damaged cells do not mend and new ones dont grow. The long-term result is loss of hearing. To prevent auditory nerve damage now wear ear protection.
Welding processes that use stainless steel SS materials can produce fumes that may contain metals eg Cr Ni known to be carcinogenic to humans. The objective was to determine the effect of in vitro and in vivo welding fume treatment on free radical generation DNA damage cytotoxicity and apoptosis induction all factors possibly involved with the pathogenesis of lung cancer. Its absolutely crucial that your workspace base metal and tools are free of debris or metal dust and shavings leftover from other projects.
Carbon steel dust even suspended in the air can cause stainless steel to rust and corrode. Its advisable to perform carbon steel welding and stainless-steel welding in separate areas entirely. According to the ASSE other common long-term health effects of welding exposure include pulmonary infection and heart disease respiratory illness lung and throat cancer stomach problems kidney disease and a variety of neurological problems.
Welding of Coated or Painted Stainless Steel When working with galvanized SS workers should be aware of zinc oxide fumes. Breathing these fumes may cause metal fume fever with symptoms similar to that of the flu nausea dizziness aches and pains fever etc. In the video the cold welder welds various shapes of objects introduces the various functions of the cold welder and the working principle of the cold weld.
In the process of fabricating stainless steel parts often encounter the deformation of parts due to welding. When welding martensitic stainless steel it is imperative that you hit an accurate preheat temperature and maintain the minimum interpass temperature the entire time youre welding. Otherwise youre likely to end up with cracks.
Yellowish-green smoke white powdery particles floating in the air and white residue around the weld are sure signs that zinc oxide is present while welding. Exposure to large amounts of the yellowish-green zinc oxide fumes will result in galvanize poisoning commonly referred to. Given these factors it is clear that austenitic stainless steels require less current of welding and greater expansion increases the tendency of warpage and deformation like cracking under resistance condition especially in the higher alloys types of stainless steelsWeld under restraint conditions especially in higher alloy types.
Galvanize poisoning is a condition that results from the over exposure to zinc oxide. Zinc oxide forms when the steels galvanized coating evaporates from the high heat used in welding. Galvanized steel is iron with a coating of zinc.
