II. Checking the home task.
Teacher: Let’s watch the presentation “Protective equipment and welder’s clothes”
Students present their works
III. Video page.
1) Pre-watching
Teacher: In what sectors is used welding works? В каких отраслях деятельности используются сварочные работы? А именно электрическая сварка?
Student 1: В строительстве зданий и сооружений, трубопроводов, промышленных объектов, мостостроении, машиностроении, судостроении, сельском хозяйстве и бытовых условиях.
Teacher: We’ve spoken about personal protective equipment and what other safety issues the welder must maintain? Мы говорим о средствах индивидуальной защиты ( одежде, каске, перчатках, респираторе), а какие другие правила техники безопасности он должен соблюдать?
Student 2: Заземление корпуса сварочных машин, регулирование напряжения,
исправность оборудования при проведении сварочных работ, изолированность работника от тока, санитарное состояние рабочего места - должно быть чистое, вентиляция помещения.
