为了在焊接车间工艺部分设计中贯彻节约方针,首先必须了解该车间工艺投资的分配情况。现将部分焊接从上表可以看出,备料设备在工艺投资中的比重最大,平均在60%以上,而备料设备中大型设备的投资平均占70%以上,所以大型备料设备的采用,必须经过周 In order to implement the conservation policy in the process design of the welding shop, it is first necessary to understand the distribution of the process investment in the shop. Now we can see from the above table that part of the welding, the allocation of equipment in the process of investment in the largest proportion, the average in more than 60%, while the allocation of equipment in large-scale equipment, the average investment of more than 70%, so the use of large-scale preparation of materials must be week
