THE INVESTIGATION OF A BUTT WELD WITH ULTRASOUND

In the case of welded joints there are defects that can not be seen with the naked eye. These defects being within the material to know if they can cause failures in the future, should be investigated and ranked in an acceptance class according to certain standards in the field. In this paper we investigate using the ultrasonic control method, the welding seam between two butt welded sheets

INVESTIGATION OF A FILLET WELF JOINT WITH ULTRASOUND

Fillet welded joints have a very high share in the industry. In the case of these welded joints, the stress concentrators at the intersection of the base material / filler material and the inner discontinuities are specific. The cumulative effect of these stress concentrators and the interior defects that inevitably occur in welding can lead to failure that may result in unpleasant consequences. Therefore, in the case of fillet welded joints, it is necessary to monitor and control the inner discontinuities. In this paper we investigate using the ultrasound control method, the fillet weld seam between those two T-welded sheets

MODIFICATION OF PERFORMANCE INDICATORS USING KANBAN METHOD AND GROWTH IN PRODUCTION LEVEL

The Kanban method is based on the principle of taking over the tasks by the team members as they become available (pull system), and not on the placement of the tasks without their being requested by the person to execute them (push system).Using the Kanban method, components are manufactured only when needed, so extra components are eliminated. As there is no extra production, waste cuts and scrap are reduced

ELIMINATION OF LOSSES USED LEAN MANUFACTURING TECHNIQUES AND KAIZEN PHILOSOPHY

Lean manufacturing is today one of the most successful production strategies for improving competitiveness. To achieve success, a healthy production system based on solid concepts and philosophies is also required. Thus, it has been decided to adopt and accelerate the Lean Manufacturing concept on every site. The Kaizen or "Continuous Improvement by Involving All" method is a teamwork methodology used to systematically solve problems and apply improvement solutions

STRUCTURAL - FUNCTIONAL ANALYSIS OF THE SOIL LEVEL MACHINE

The soil leveling machine is of half – carried type and it works, as unit, with the wheeled tractor (or caterpillar tractor). The leveling plane is established by the rear wheels of the tractor and by the wheels of the hind train of the machine. The positive and negative soil dislevelments are given against the leveling plane. In the paper there are established the displacements of the mechanism for the automatic working regime, in which the cutting blade is execution element

Implementation of an occupational stress Control Model

Occupational stress is an enemy of society, a problem that requires a deep research to control stress more effectively. The case study presented in this article consists of a model control regarding occupational stress. The experimental part of this study involved interviews with 15 employees, 9 females and 6 males aged between 25-55 years. Participants described stressful situations at work. Time allocated for each subject was 45 minutes per interviews. The model was implemented based on the job content stressors, effects of stress (physiological, psychological, behavioural) and interviews results. Future directions in stress research is to identify the way to have control in the workplace because, in my opinion, that it is the key factor for good results and health
