Welding is a critical and important operation in various industries. The operation produces poisonous fumes and gases that can cause respiratory problems towelding technicians. National Institute of Occupational Safety and Health estimates that at least 2 million workers arerecruited as welders. This makes it necessary to preserve and protect the well-being of researchers by measuring the level of fumes inhaled by researchers. A descriptive-cross sectional study was carried out in welding workshops within the Nahav and Hamadan City of Iran. In order to measure the density of welding fumes in respiratory spaces, NIOSH 7300 and 7048 were followed. The collected data were compared with NIOSH and ACGIH standards and the results were presentedin tables and diagrams. As shown by the results, out of 15 specimens taken from the respiratory system of subjects, 3 (20%) met the standards and 12 (80%) exceeded the standards. This result indicated an imperative need to find alternative processes, provide ventilation systems for research shops and welding spots, equip the workers with respiratory masks, carry out routine checkups so that their exposure to welding fumes can be reduced.

Fiabilitate şi Durabilitate, 2012
This paper presents research conducted on the contents of fumes resulting from welding processes with emphasis on micro various metallic and nonmetallic elements involved in these fumes. It also presents the main health effects of welders and operators working in the welding stations. Are risks that may occur due to micro chromium, nickel, iron, manganese, silicon, fluorine, zinc, aluminum, copper, cadmium, lead, molybdenum, cobalt, vanadium and others.
Respiratory Effects from Welding Fumes in Automotive Industries in Malaysia
Lung function and persistent symptoms among 53 welders in Plant 1 and 44 welders in Plant 2 of automotive industries in Selangor, Malaysia were investigated. Lung functions of 52 non-welders subjects working in the similar industries were also investigated. Interviews were conducted to gathered data on persistent symptoms, smoking habits and demographic data of the welders. Lung function test by using handheld spirometer were conducted for both welders and non-welders. Metal fumes samples collected from the breathing zone of the welders were analyzed by inductively coupled plasma mass spectroscopy (ICP-MS). None of the metal elements concentration was exceeding the permissible exposure limit (PEL) for both plants. However, the odds of the more than 5 years working welders to experience 'sore or dry throat' are 3.38 times higher than less than 5 years working welder in Plant 1. In addition, statistical analysis showed significant mean difference of lung functions between weld...
Lung Function Status of Workers Exposed to Welding Fume: A Preliminary Study
The Indonesian Biomedical Journal, 2016
BACKGROUND: Exposure to welding fume in the workplace was associated with lung function disorders and occupational asthma. In this study, we determined lung function parameters in men workers exposed to welding fumes from heavy equipment manufacturer. This study is a preliminary study of biomonitoring program in worker exposed to welding fume as our main study. METHODS: A study with case-control design, random study, was conducted among welder (59 subjects) and non-welder (34 subjects) with more than one year experience in the same job task in a heavy equipment manufacturer. All subjects completed physical examination, informed consent, questionnaire and lung function status. Lung function status was measured by spirometer with vital capacity (VC), forced vital capacity (FCV), forced expiratory volume in one second (FEV1) and ratio of FEV1/FVC as test parameters. Linear regression model was developed to identify the risk factor of lung function parameter status using age, working pe...

Introduction: About 11 million workers are welders worldwide, and more than 110 million workers are exposed to welding-related jobs. As many as 75.6% of welding workers in Pontianak, West Kalimantan, Indonesia, suffer from abnormal pulmonary function due to exposure to welding fumes. This study analyzed some risk factors and their sensitivity of abnormal pulmonary function in welding workers. Methods: This study is a meta-analysis article. Data sources were obtained from articles published online on Google Scholar, Science Direct, Pubmed, and Springerfrom 2010 to 2020. A total of 15 articles were selected for meta-analysis using JASP version 0.9.2 software. Results and Discussion: Results showed pooled prevalence ratio (PR) values of long-exposure variables of 1.954 (95% CI = 0.31– 1.03), smoking habits of 2.159 (95% CI = 0.33–1.22), USE of PPE 1.491 (95% CI = -0.50–1.30) and exposure to welding fumes 2.271 (95% CI = 0.52–1.12) in welding workers with abnormal pulmonary function.
